Excretion System On Animal

Excretion System on Animal a. Excretion Tool on Insects Group animal insect or insect own tool excretion Which called reed malpighi.Reed malpighi This shaped reeds fine colored yellowish Which called tubule malpighi. A bunch reed malpighi bound on end anterior intestines behind. Like shown on picture following. Method Work reed malpighi or tubule malpighi is with method absorb substances Which dissolved in blood through wall tubule. In in tubule, fluid Which enter selected, substance Which beneficial absorbed For returned to blood including water until remaining waste Which shaped congested, that is sour tendon. Tubules malpighi No own channel output. By because That, sour tendon distributed to intestines behind. With method like This, substance remainder metabolism will thrown away together feces. With thereby, can prevent grasshopper For lost water from in his body. Form excretion This No there is on excretion animal other. b. Excretion System on Fish Based on environment place his life there is two type fish, that is fish sea and freshwater fish. Differences in the salinity of the environment where the fish live cause difference on Work kidney from each fish. On fish water bid, environment hypotonic cause water enter continously to in body. So that spared from dilution fluid body, kidney fish must Work hard emit water This in form urine. Blood Which bring water And salt- salt will enter capsule Bowman through glomerulus. On capsule bowman will happen filtration. Substances Which Still needed absorbed return by arteries oerytubulary Which surround tubule. After absorption salts body finished, formed urine Which on in fact No more than water just, because part big waste nitrogen thrown away in a way diffusion through gill. Can said that for fish water bid, kidney is tool balance water, besides as tool excretion. From kidney, urine will streamed to channel urine going to cloaca or even direct to outside through pores/holes urinaria, side by side with hole dirt- his. On a number of type fish, especially fish male, channel urine unite with channel reproduction. The pocket called sine urogenital. Marine fish face a different problem. In fact, the salinity is high cause fluid his body sucked to outside continously. On fish bony vulnerable, like fish shark, his kidneys more Lots absorb urea return to in his blood. This done so that pressure osmosis blood The same with pressure osmosis water sea. Circumstances isotonic This can prevent it flows fluid body to outside. Rate urea in blood shark almost 80 time fold rate urea on vertebrates other. Function kidney fish sea The same with kidney vertebrates land, that is filter waste nitrogen, salts, And A little very water. Difference only there is on rate the urea. Fish sea Which bony hard like milkfish for example overcome lost water with drink water in a way continously, whereas salt Which follow swallowed will returned to sea through transport active by gill. Temporary That, kidney will as little Possible form urine. So that formation urine No too Lots, fish sea own glomerulus Which very small. However, There is a number of type fish sea Which No own glomerulus. Salts And waste nitrogen issued through tubule And system portal renal Which Good. c. Excretion System on Frog Amphibian own kidney type opistonefros. Same case with fish water bid, kidney Also works For balance water in in body. Kidney frog Also must Work adapt self with method life frog Which when- time in water And anytime in land. On moment in land, Genre blood on glomerulus limited. Substances throw it away will absorbed by tubule through system portal renal. Besides That, frog own pocket urinary. On moment lack water, water in pocket urinary absorbed return to in blood. d. Excretion System on Reptiles Reptile kidneys are of the metanephros type, the shape of the kidney different. In snakes and lizards the kidneys are long and narrow. Position second kidney No Again side by side in left And right body, However kidney Which One located in part behind kidney Which other. Snake, crocodile, And monitor lizard No own pocket urinary. For adapt with environment Which dry, third member reptile the change his urine become sour tendon And throw it away in form dry like pasta white. Possible You Once see dirt gecko or house lizard in House Which the color half black And the end white. Part black is feces (feces) And Which white sour tendon. So, part big member reptile throw away waste nitrogen without lost water. This important Because they environmental Which very dry And the closed skin scale thick. On lizard And turtle, kidney continue urine to urinary bladder (urinary bladder) through short ureters. Urinary bladder continue Again to cloaca. Turtle certain own two pocket addition on pocket his urine as tool help respiration. On turtle female, second pocket addition That sometimes containing water For wetting land in the place lay eggs so that soft moment dug. e. Excretion System on Bird (Aves) Because flight habit so cause bird effective arrange weight his body. So that No become burden, bird No own pocket urinary. Urea thrown away in form sour tendon. Only bird camel (ostrich) Which own pocket urinary. Sour tendon Which issued together feces the color white And like pasta. In kidney bird No There is system portal renal, all over absorption waste done by glomerulus. So, although glomerulus small, However his activities tall Because No There is help from system portal renal.
