Name two of The body cavity
Functions
1. provide more room for organ
development
2. Provide more surface area for diffusion
3. provide an area for storage
4. often act as hydrostatic skeletons
5. provide a vehicle for eliminating wastes
and for reproduction
6. Facilitate increased body size.
Name some
benefits of
having a body
cavity?
advantages of possessing a body
cavity include more room for
organs, more internal surface
area, and storage areas.
Further advantages include the
possession of a hydrostatic
skeleton, aiding in elimination of
reproductive and excretory
products and wastes, and an
increase in body size.
Triploblastic Organization.

tissue layers derived from
the embryonic ectoderm,
mesoderm, and endoderm.
