Haemocoelomic system➫ The body cavity found in many invertebrates where the hemolymph circulates through. 


❱ It contains blood or hemolymph and functions as part of the circulatory system.

❱ The remainder of its journey takes place within the body cavity called the hemocoel.

❱ Blood is pumped by a heart into the
body cavities, where tissues are surrounded by the blood.

❱ In most vertebrates the oxygen is supplied to different organs of the body through capillaries in a closed circulatory system.
