The function of the heart is to receive the deoxygenated blood from all parts of the body and to pump it for aeration to the gills. Such a type of the heart is designated as the venous or branchial heart, because only the deoxygenated blood circulates through its different parts.

heart is a muscle that pumps blood to all parts of your body. The blood gives your body the oxygen and nourishment it needs to work properly.
