BIOB34H3 Lecture Notes - Distal Convoluted Tubule, Peritubular Capillaries, Tubular Fluid
Document Summary
The change in the tissue you see is the medulla in the inner side. The medulla leads to another structure called the renal pelvis, where the urine produced by the kidney initially collects. Renal pelvis continues on to form ureter which takes the urine towards the bladder. The kidney has a blood supply that comes through the renal artery, and the renal vein carries the blood away from the kidney. The renal artery is one of the major branches coming off the aorta. The blood coming to the kidneys needs high pressure to allow filtration. Not all vertebrates have kidneys that look just like mammals. In the pig kidney you can see the similarity in structure between itself and the human kidney in the previous slide. If you look at other vertebrates like the snake and the fish, it"s different. They don"t have the compact kidney bean shape found in mammals; their kidneys tend to be longer diffused organs.
