Vedclass · Answer

(A) In organisms with an open circulatory system,such as many arthropods and mollusks,blood is pumped into body cavities called sinuses or hemocoels. Because the blood is not confined within a continuous network of vessels,it flows at a low pressure. Furthermore,the flow is irregular because it is not driven by the high-pressure,rhythmic contractions of a closed vascular system,but rather by the movement of the body and the heart's pumping into open spaces. Therefore,the blood pressure in blood sinuses is low and irregular.
