Document Summary
Slide 2: there are two distinct sections. The blood coming to the kidneys needs high pressure to allow filtration. Slide 3: 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. In the fish you can see long diffuse kidneys, and in the snake it starts to be a little more compact, and as it gets closer to mammalian kidneys it becomes more compact. This occurs in other types of organs as well because they become more compact as you move up from fish to reptiles and to mammals. In the fish or snake kidney, there"s no distinction between the cortex and medulla.
