Mention the advantages of coelom over pseudocoelom.

Explanation

Advantages of coelom over pseudocoelom :
1) Visceral organs of eucoelomates are muscular (because of their association with mesoderm) and so they can contract and relax freely independent of the muscular movements of the body wall in the coelomic space, e.g. : peristaltic movements of alimentary canal.
2) Gametes are released into the coelom in some invertebrates (which do not have ginoducts) and in the female vertebrates.
3) Coelomic fluid receives excretory products and stores them temporarily before their elimination.
4) In the eucoelomates, the mesoderm comes into contact with the endoderm of the alimentary canal, and it causes regional specialization of the gut, such as the development of gizzard, stomach etc., This is referred to as "primary induction.. In the case of the pseudocoelomates, due to the absence of such a contact between the gut and the mesoderm, the wall of the gut does not show complex and highly specialized organs.
