What is the function of coelom in an earthworm?

Answer 1

Coelom is a cavity that develops during embryonic development of animals. The cavity develops from tissue derived from the mesoderm germ layer. The fluid-filled cavity (coelom), cushions the internal organs and allows for their expansion and contraction.

Answer 2

A coelom is a fluid filled cavity within the mesoderm, it can be seen as the digestive track of an earthworm. Coelomic fluids assist in locomotion and regulation of fluid transfer through the body wall. It can also serve as a temporary food storage, excretion of nitrogen-containing wastes and for maturation of gametes.

Answer 3

Coelom provides space for different organs like heart, lungs, kidneys etc., Presence of coelom also gives flexibility of the body so that animal can move in direction freely. Depending upon type of coelom present, the animals are divided into three groups

1. Acoelomates Eg: Platyhelminthes- Here the body cavity is filled with mesenchyme, hence do free movement. The body stays rigid.

2. Pseudocoelomates Eg: Nematyhelminthes (Round worms)

3. Eucoelomates

The Eucoelomates are further divided into two groups Schizocoelomates and Enterocoleomate.

Schizocoelomates - Eg: Annelida, Arthropoda and Mollusca

Enterocoelomates - Eg: Echinodermata, Hemichordata and Chordata

Answer 4

The intestines help carry the earthworm's waste to the anus, where it is expelled from the worm.
