Hemocoel

From Wikipedia, the free encyclopedia

A Hemocoel is a cavity or series of spaces between the organs of organisms with open circulatory systems like most arthropods and mollusks. A combination of blood, lymph, and interstitial fluid called hemolymph circulates through the hemocoel.

A Hemocoel is also the space in the connective tissue compartment derived from the embryonic blastocoel with contributions from mesoderm, filled with blood.
