What is an open circulatory system?
Answers
Open circulatory system is the one in which blood does not circulate only inside blood vessels but it also falls in cavities that irrigate tissues. In the open circulatory system the blood pressure is low and generally the blood (called hemolymph) has low cellularity.

Arthropods, molluscs (the cephalopods are exception) and protochordates have open circulatory system.   Your Comment
