Question

Compare
proonephros, mesonephros and metanephros
kidney.
​

Answer 1

Answer:

proonephrous

The pronephros develops from the intermediate mesoderm, as do the later kidneys. It is a paired organ, consisting of a single giant nephron that processes blood filtrate produced from glomeruli or glomera- large embryonic glomeruli. The filtrate is deposited into the coelom.

mesonephros

The mesonephros (Greek: middle kidney) is one of three excretory organs that develop in vertebrates. It serves as the main excretory organ of aquatic vertebrates and as a temporary kidney in reptiles, birds, and mammals.

metanephros

Kidney development, or nephrogenesis, describes the embryologic origins of the kidney, a major organ in the urinary system. Nephrogenesis is often considered in the broader context of the development of the urinary and reproductive organs.
