Ultrastructural characteristics of renal corpuscle evolution in vertebrates.

Peculiarities of renal corpuscle's structural organization of a number of animals representing various classes of vertebrates have been studied on submicroscopic level at the stages of excretory organs formation: pronephros, mesonephros and metanephros. The fact has been established that side by side with the common structure there have been specific peculiarities due to the level of evolutional development and character of habitat.
