ii) OPEN TYPE CIRCULATORY SYSTEM-

Open type circulatory system( evolved in insects, molluks and other invertebrates) pump blood into a hemoceol with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into blood cavities, where tissues are surrounded by blood.

iii) CLOSED TYPE CIRCULATORY SYSTEM-
