Lizard and Snake Excretion Lizards and snakes are different to mammals in several aspects of nitrogenous excretion. Uric acid is the primary catabolic end-product of protein, nonprotein nitrogen and purines in reptiles. It is synthesised in the liver and excreted by renal tubular secretion Respiratory system. All reptiles breathe using lungs. Aquatic turtles have developed more permeable skin, and some species have modified their cloaca to increase the area for gas exchange. Even with these adaptations, breathing is never fully accomplished without lungs. Lung ventilation is accomplished differently in each main reptile group

The purpose of this study was to examine the morphology and histological structure of excretory system in this species. To perform this task, a number of 12 lizards (male and female) were collected from their natural habitat and transferred to the laboratory where their kidneys and excretory ducts were. Excretory system of reptiles that live mainly in water. excrete ammonia, it can be diluted with water and expelled from body. excretory system of retiles that live mainly on land. convert ammonia to uric acid, a less toxic version that does not have to be diluted. Water from the urine is reabsorbed by the cloaca They excrete nitrogen in the form of urea and cannot produce urine more concentrated than the blood. Their skins are permeable to water. On land amphibians are liable to lose water very rapidly by evaporation. In fresh water they suffer entry of water by osmosis, which is counteracted by the excretion of a large volume of dilute urine The excretory system consists of two kidneys, each with a ureter that carries urine produced by kidneys to the cloaca where it leaves the body. The cloaca is the external opening that services all systems that excrete something. Birds are part of a limited group, including insects, reptiles, birds, and some dogs that excrete uric acid

Comparative Anatomy: Excretory System of Reptile, Bird and

Comparison with the excretory system of other animals . The excretory system of the birds retains some similarities with that of the reptiles, in that both have cloaca and the urine is deposited in a semi-solid state creamy. However, the location, shape, and color of the organs composing both systems differs widely In reptiles and birds, the excretory system is uricotelic since uric acid is insoluble, less toxic and suitable to be stored within the eggs where their embryos develop. 9. How do the embryos of placental mammals excrete nitrogenous wastes? Placental animals, including embryos, excrete urea. In the adult placental mammal urea is excreted.

Amphibians - The Excretory Syste

The Malpighian tubules are a key insect excretory organ. Excretion. Excretion is the process whereby an organism eliminates metabolic wastes and unwanted chemicals from its system. Metabolism is. the sum total of all the chemical reactions occurring in the cells and body. Some products of these metabolic reactions are toxic Modes of Excretion. Based on the excretory product, five modes of excretion are known in animals. They are: Ammonotelism (Type of excretion- ammonia) Ureotelism (Type of excretion - urea) Uricotelism (Type of excretion - uric acid) Aminotelism (Type of excretion - amino acids

Birds and reptiles have even developed uric acid, which is a more concentrated and safer form of urea. As a whole system, every part and organ of the excretory system can be functioning at the same time to remove wastes from the body. However, if the structure of the excretory system gets damaged by disease, many bad consequences can ensue. Even among some lower organisms, excretion occurs through specialized organs, such as the nephridia seen in earthworms. In others, excretion happens through diffusion. In the higher phyla and classes of the animal kingdom, animals such as fish, birds, reptiles, etc. have a specific excretory system in place to get rid of the metabolic wastes Their excretory systems are capable of fully processing waste and excreting it as urine and feces. A squid (Teuthida) is another example of a mollusk. Contaminants are removed from the body and sent to the bladder. From there the pulsing of the blood stream causes the bladder to expand and contract, allowing waste materiel to leave the body

Excretory system is one of the most important biological systems in our body along with the respiratory system, circulatory system, digestive system, etc. In this article, we will come to know about different excretory organs present in humans and their functions and how urine is formed inside our body Reptiles' lungs are the main component of their respiratory system, just as they are in humans, birds and land-dwelling amphibians. However, among the main types of reptiles, there are some distinct differences in the details of their respiratory system functioning. Regardless of the differences.

The excretory canals join with other canals to form excretory tubules. Fluid from the excretory tubules leaves the body through pores. In earthworms, members of the phylum Annelida, the excretory system consists of structural units called nephridia (the singular is nephridium) The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseou Excretory System of Man: The excretory system of man consists of a pair of kidneys, a pair of ureters, a urinary bladder, and a urethra. In both birds and reptiles, the ureters and rectum open into a sac called cloaca which stores both urine and faeces and reabsorbs water from them The excretory system in humans being gathers and drains out the wastes from the body.The human excretory system consists of a pair of kidneys, a pair of ureters, a urinary bladder and a urethra. The waste substances dissolved in the blood are carried to the kidneys for filtration Explain how different excretion systems function. Microorganisms and invertebrate animals use more primitive and simple mechanisms to get rid of their metabolic wastes than the mammalian system of kidney and urinary function. Three excretory systems evolved in organisms before complex kidneys: vacuoles, flame cells, and Malpighian tubules

Nitrogenous Waste in Terrestrial Animals: The Urea Cycle. The urea cycle is the primary mechanism by which mammals convert ammonia to urea. Urea is made in the liver and excreted in urine. The overall chemical reaction by which ammonia is converted to urea is 2 NH 3 (ammonia) + CO 2 + 3 ATP + H 2 O → H 2 N-CO-NH 2 (urea) + 2 ADP + 4 P i + AMP.. The urea cycle utilizes five intermediate steps. Nitrogenous Waste in Birds and Reptiles: Uric Acid. Birds, reptiles, and most terrestrial arthropods convert toxic ammonia to uric acid or the closely related compound guanine (guano) instead of urea. Mammals also form some uric acid during breakdown of nucleic acids The Excretory system : An important chapter for students of ICSE 10th following are the important previous year questions from chapter and solutions of back exercises of concise biology 10th. A. MULTIPLE CHOICE TYPE (Select the most appropriate option in each case) 1. Excretion primarily involves (a) removal of all by products during catabolism Reptiles have kidneys and a well-functioning excretory system. But since their skin is water-tight, they do not produce urine. They possess a colon for water absorption. Fishes are known to have a two-chambered heart while reptiles have a three chambered heart, two auricles and one partially divided ventricles

The unicellular organisms and organisms with a single layer of cells (lower organisms) generally do excretion through diffusion. In the organisms with multiple layers of cells, excretion is done through a complex excretory system. In vertebrates, the excretory system has kidneys, urethra, and urinary ducts associated with it Reptile; Excretion of waste: Excretion takes place through the gills: Have a defined excretory system with well-functioning kidneys. Limbs: Their limbs are modified as fins: Some have proper forelimbs and hind limbs while species like snakes do not have them: Skin: Usually have bony and skinny scales: Rough and dry skin without glands: Respiratio the function of the excretory system is to remove wastes from the body in liquid form while retaining as much water and nutrients as necessary to maintain homeostasis. In animals living surrounded by water, ammonia and other wastes are able to simply diffuse out of membranes in an organisms body and into the water (ammonia is highly soluble in. The phylum's excretory system is marked by the kidney. The kidney is the main organ and is found within all of the species. That is the only considerable similarity among the species.

Common Disorders of the Excretory System. All living organisms consume food to generate energy that allows them to perform their biological processes. At the same time, they have certain by-products that are generated during these processes and these need to be expelled.This is known as excretion.In the human body, a specialized system is present, known as the excretory system Excretory System in Amphibians. The most common type of waste produced through metabolic processes is nitrogenous wastes. Nitrogenous wastes form from the natural breakdown of proteins in the body. The excretory system in humans and fish are responsible for regulating the chemical composition and water balance of body fluids. It does so by removing metabolic waste from the blood, and keeps the appropriate amount nutrients, water, and salt. The blood passes through individual filters called nephrons. T The nephron includes a basic filter.

The Excretory System removes waste that collects in the body during metabolism. Metabolism is when the bady takes in air, food and liquid. Flatworms excretory systems are a network of fine protonephridial tubules embedded within the mesoderm.Branching off of this network are the flame cells The kidneys of reptiles, birds, and mammals are not segmental. Each animal has only a single pair of kidneys. Vertebrate kidneys also remove waste only from the blood supply—not from the body cavity. These animals all have different excretory systems. Match the animal to its excretory system and then click Submit. That's right

T he primary organs in the excretory system of a slug are the nephridia. These organs produce either ammonia or uric acid as a waste product. The nephidrium has an important role in maintaining water balance in certain species. In some species, additional organs include pericardial glands in the body cavity and digestive glands opening into the. Chapter 44 Osmoregulation and Excretion Lecture Outline . Overview: A Balancing Act. The physiological systems of animals operate within a fluid environment. The relative concentrations of water and solutes must be maintained within narrow limits, despite variations in the animal's external environment Answer the following questions for the Excretory System: In mammals, birds, and reptiles, the kidneys lie in the pelvic region and filter only the bloodstream. The urine-forming unit of the kidney is called the nephron, which is a coiled tubule full of complicated twists and turns and too small to be seen by the naked eye. Each human kidney.

Our excretory system consists of kidneys, blood vessels that join them, ureters, urinary bladder and urethra. They help produce and excrete urine. There are two bean-shaped kidneys that lie in the abdominal cavity, one on either side of the vertebral column. The kidneys are reddish brown. Each of them is about 10 cm long and weighs about 150 g excretory system as they are the body's filtration system The kidneys help maintain a balance among the elements inside the body-this balance is referred to as homeostasis The kidneys perform the following important jobs: They remove urea and other wastes from the blood They regulate the amount of water in the circulatory system 3,373 excretory system stock photos, vectors, and illustrations are available royalty-free.

Excretory and Reproductive Systems Excretory and reproductive systems each have important but different functions in animals. The excretory system maintains water, ion, and nitrogen balance within the body and eliminates wastes. The reproductive system creates new individuals of a species. Both the excretory and reproductive systems are under endocrine control but are also influenced by the. Annelida. In all Annelids the excretory system uses a two-stage filtration process during which waste materials and fluids are extracted and then filtered again to consume left over re-usable substances while deposing of toxic and drained materials as urine. Members of the Annelida phylum could be capable of using one of two different methods. Their excretory system consists of two tubules connected to a highly branched duct system. The cells in the tubules are called flame cells (or protonephridia ) because they have a cluster of cilia that looks like a flickering flame when viewed under the microscope, as illustrated in Figure 41.10 a Excretory system in human consists of a pair of kidneys, a pair of ureters, urinary bladder and urethra (Figure. 8.2). Kidneys are reddish brown, bean shaped structures that lie in the superior lumbar region between the levels of the last thoracic and third lumber vertebra close to the dorsal inner wall of the abdominal cavity. The right kidney. Excretion in Animals; significance of excretion, modes and types of excretory wastes in different animals Excretion: It is defined as elimination of metabolic wastes by an organism at exchange boundries such as plasma membrane of unicellular organisms and or excretory tubules (flame cell, nephridia, malphigean tubules, nephrons etc) of multicellular organisms

Skeletal System All reptiles have a hard, bony skull to protect their brains. They have a long vertebral column to protect their nerve chord, a sturdy rib cage to protect vital organs. Muscular System All reptiles mainly use their muscles as locomotion. Snakes also use their muscles to move prey that they have consumed. The excretory system of the ascaris suum is ureotelic, meaning its excretes excess nitrogen as urea. This process is controlled by the renete cell, which is connected to large and small canals. After food is collected and digested, the canal ends are closed. The wastes is then processed through the excretory pore

Accessary Excretory System Organs 1. Liver. Although considered a secondary, or accessary excretory system organ, the liver plays a vital part in keeping the body clean. Harmful poisons and chemicals that are either produced in the body or consumed are broken down and detoxified by the liver. For example, a bi-product of the metabolic process. The excretory system is a collection of organs that work in unison to remove waste and other harmful products from the body. Each kidney consists of one million nephrons. A nephron is a basic filtering unit that regulates the amount of water within the body. Blood filtration also takes place within the nephrons Figure: Excretory or Nephridial System of Earthworm.Image Source: Study and Score. B. Integumentary nephridia. These nephridia are found in the entire inner or parietal surface of the body wall in each segment, except for the first two Excretory System - The excretory system of the body controls the fluids of the body, including removing excess and unnecessary fluids from the body. The organs include the kidneys, lungs, liver, and the skin. Each of the organs have a responsibility in the system, but the kidneys are the main organs of the excretory system. The kidneys control the fluids of the body

Excretory systems regulate the chemical composition of body fluids by removing metabolic wastes and retaining the proper amounts of water, salts, and nutrients. Components of this system in vertebrates include the kidneys, liver, lungs, and skin. Not all animals use the same routes or excrete their wastes the same way humans do Uric acid is the main nitrogenous excretory product of reptiles and birds whereas urea is the main excretory product of humans. The key difference between urea and uric acid is that urea in humans is excreted with urine as a liquid, while uric acid is excreted in birds and reptiles as a solid with fecal matter. Image Courtesy: 1 The human excretory system functions to remove waste from the human body. This system consists of specialized structures and capillary networks that assist in the excretory process. The human excretory system includes the kidneys and their functional unit, the nephron. The excretory activity of the kidneys is modulated by specialized hormones. Process of excretion of urea. Ureotelic animals: Cartilaginous fishes, terrestrial & semi-aquatic amphibians (frogs, toads etc.), aquatic & semi-aquatic reptiles (alligators, turtles), mammals etc. In liver, NH3 is converted into less toxic urea. So, it needs only moderate quantity of water for excretion Excretory cells known as flame cells developed in flatworms, while nephridia developed as excretory cells in annelids. Flame Cells of Planaria. Planaria are flatworms that live in fresh water. Their excretory system consists of two tubules connected to a highly-branched duct system that leads to pores located all along the sides of the body

Excretory System. When our cells perform their functions, certain waste products are released in to the blood stream. These are toxic and hence need to be removed from the body. The process of removal of wastes produced in the cells of the living organisms is called excretion. The parts involved in excretion forms the excretory system Disorders of Excretory System: Human excretory system includes kidneys, ureter, urinary bladder, and urethra. A healthy kidney and other parts of the excretory system are important for our overall health. If the kidneys are once damaged, they cannot be reversed back. So, we should take proper care of it This system is generally responsible for the elimination of metabolic waste products (nitrogenous waste products in the form of urea, etc.), excess of salts and water from the body. The organs of excretion in rabbit are a pair of kidneys, ureters and a urinary bladder. Kidneys: The kidneys are metanephric and main organs of excretion. 1 Excretion takes place with the help of four body systems. In the urinary system, the kidneys work to rid the body of water and toxins. They also eliminate electrolytes and nitrogen compounds. Ridding the body of carbon dioxide waste through respiration, the lungs form the respiratory lever of the excretory system

Anatomical and Histological Study of the Excretory System

The excretory system is a structure formed by different organs and whose primary function is to eliminate the excess of unnecessary materials from body fluids. The objective of this system is to keep the homeostasis or chemical balance and avoid pain in our body. For this, the waste products are removed from the metabolism, and the body is. Excretion helps in removing toxic wastes from our body and it also plays an important role osmoregulation i.e. the maintenance of the homeostasis of the body. Carbon dioxide, water, nitrogenous compounds such as urea, uric acid and excess salts are some common excretory products. Solution C.3 Excretion is the physiological process of elimination of metabolic waste from the body. The excretory products include amino acids, urea, uric acid, carbon dioxide, water, and ammonia. Some Molluscs and Echinoderms excrete waste products from the body in the form of amino acids

Excretory system in humans The excretory system in human beings includes a pair of kidneys, a pair of ureters, a urinary bladder, and a urethra. This is also known as the urinary system. 1) Kidney Kidney is an excretory organ present in the human body. Kidneys act as excretory organs and also control the balance of water and mineral ions in the. excretory system in a sentence - Use excretory system in a sentence and its meaning 1. The kidneys and excretory system are much the same as in other reptiles, but crocodilians do not have a bladder. The lacrimal system is made up of a secretory system, which produces tears, and an excretory system, which drains the tears The excretory system contributes to this control by dictating what molecules are excreted or absorbed by the body. If the pH of blood is too low, the excretory system reabsorbs bicarbonate and excretes hydrogen ions. Similarly, if the pH of blood is too high, the excretory system reabsorbs hydrogen ions while excreting bicarbonate Reptile Bodily Systems. All reptiles except snakes have features like bony skull, spinal column, rib cage, and the bones that form the framework of the limbs. Reptiles have spinal bones in the pelvic region too. They have a well-developed brain and a central nervous system too. The breastbone protects the heart as well as the lungs The main aim of the study was to prove the compensative effect of intestine for renal function. Rat kidney was impaired by intragastrically administrating adenine (400 mg per day for 5 days). Intestinal tract was harvested and equally divided into 20 segments except cecum. Kidneys were harvested and histologically examined with hematoxylin-eosin staining kits

Each of these organs is responsible for excretion of different waste and plays a different role in our body. Here I will be highlighting the role of each. The excretory systems of many birds are similar to those of some reptiles. Nitrogenous wastes are removed from the blood by the kidneys, converted to uric acid, and depositd in the cloaca. there, most of the water is reabsorbed, leaving uric acid crystals in a white, pasty form The Excretory system is a passive biological system that removes excess, unneeded material from an organism's body fluid to preserve internal chemical equilibrium and prevent damage to the body
