Animals' excretion

Excretion

1. EXCRETORY SYSTEM IN ANNELIDS

2. EXCRETORY SYSTEM IN ANNELIDS In annelids Annelids are round, segmented worms, like the earthworm. The excretory organs of the annelids are nephridia . These are composed of a tube that opens into a hole to the outside, called nefridioporo . Some species have a pair of nephrids in each segment of the body and others only one pair

3. PARTS: The nephridiums :(from Latin nephridium ) are excretory organs of invertebrate animals with a function analogous to that of the kidneys of vertebrates. They eliminate metabolic waste from the body of the animal. They appear in many animal edges. Two types are distinguished, protonephridia and metanefridios . EXCRETORY SYSTEM IN ANNELIDS

4. Annelids The organs of excretion in earthworms are metanefridios . These metanephridios are constituted by nephrostomas and complex tubules, that before opening to the outside they form a dilation called bladder. The nephridporos are located outside, some culminate in the intestine ( enteronephridios ). To perform the excretion, the coelomic fluid of the anterior somite penetrates through the nephrosome , and as it passes through the tubule, it is transformed into urine. As the urine is formed along the tube, the concentrations of the elements that form it vary, which indicates which substances are reabsorbed and which are eliminated, as well as the control of the water according to the needs of the organism. They eliminate mainly urea EXCRETORY SYSTEM IN ANNELIDS

6. what is excretion? Is the biological process that collect waste products from metabolic functions. Is in charge to remove toxins and wasteds from body and the amount of fluid and solt in the body.

7. what is osmoregulation? Is the process that keeps balance of an organism body fluids, this process is necessary for all living things. The osmoregulation keep water enough to support life. In most living the excretory system develop osmoregulation process.

8. EXCRETION in INSECTS The insects have a special system formed by some tube called malpighi tubes that operate all together. They operate in conjunction with glands in the wall of the rectum, they form urine that go to the large intestine and float in the hemocele in where they capture the waste products and end in the final of the tube where are evacuated and eliminated in the urine. The urine of insects are uricotelism that means that the insects urine is mostly composed of uric acid an that happened because they reabsorb water depending on his environment are if it is hot reabsorb almost all of the water leaving the urine almost dry as opposed to other insects which live in holders wet and your urine is more liquid

11. What is excretory system ? Is responsible for eliminating toxic substances and waste products from living things body. The excretory system is formed by the urinary system (formed by the kidneys and the urinary tract), the lungs and the skin.

12. Excretory system in amphibians the excretory system of amphibians is formed by kidneys, excretory conductors and urinary bladder, the kidneys are bean-shaped organs that filter the blood through the nephrons, the excretory conductors are Anatomical structures through which the urine circulates in the body, from the kidneys to the outside and the urinary bladder is the one that stores the urine till you can feel it.

13. WHAT IS OSMOSIS? Osmosis is the passive transport of water and ions . Pass a solution from a solution of high concentration to a lower concentration

14. Osmosis in Amphibians Osmosis is a process that is equal in all animals but the difference in amphibians is that because of their bare skin the pass of water and ions is easier making the susceptibler to lose all the liquids inside .

15. WHAT IS OSMOREGULATION? Process by which cells and simple organisms mantain fluid and electrolyte balance with their surroundings

16. OSMOREGULATION IN AMPHIBIANS They have a wáter intake that moisturizes them and a passive loss of salts with a greater effect in the aerial área by having a bare skin to compensate them , they urinate ( Kidneys adapted to the great filtration ) or present an active uptake of salts by scattered cells in the skin similar to chloride cells

19. OSMOSIS Passage of a solvent (such as water) from a lower-concentration solution to a higher-concentration solution, through a semi-permeable membrane (that allows the solvent to pass but not what is dissolved in it) separating the two solutions. The flow of solvent stops when both solutions become equal in concentration. In nature, osmosis is an essential process by means of which nutrients are delivered to the cells.

20. osmoregulation Is the process that keep balance of an organim body fluid, this process is necesary for all the living things osmoregulation process is developed by excretory sistems.

21. excretory system of fish The primary excretory organ in fishes, as in other vertebrates, is the kidneys. In fishes some excretion also takes place in the digestive track , skin, and especially the gills most fish release their nitrogenous wastes as ammonia. Some of the wastes diffuse through the gills into the surrounding water. Others are removed by the kidneys excretory organs that filter wastes from the blood. Kidneys help fishes control the amount of ammonia in their bodies. Saltwater fish tend to lose water because of osmosis. In saltwater fish, the kidneys concentrate wastes and return as much water as possible back to the body. -oesophagus -anus -stomach -pyloric ceca -primary -gills Kidney -mouth -intestine -rectum
