Answer:
True
Step-by-step explanation:
The coelom is the main body cavity found in a group of multi-cellular animals known as metazoans that functions in absorbing shocks, supports immune system, acts as hydrostatic skeleton, and or facilitates a kind of transport system in the animals.
The coelom arise from the mesoderm and as a result, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
