Question

compare closed and open circulatory system

Answer 1

Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities. Theopen circulatory system is common to molluscs and arthropods.

Open Circulatory System. The second type of circulatory system that we are going to examine is the open circulatory system. This system is much less complex than the closed system. Although an open circulatory system also contains a heart to pump the blood, not all of the vessels are connected to each other.
The volume of the blood is lower than the blood in animals with an open circulatory system. The blood is pumped into the blood vessels with the help of the heart. ... An open circulatory system is one where there is no true heart or capillaries. Instead of the heart, blood vessels pump the blood with force.
