Animals having open circulatory system POSSESSES – (1) coelenteron (2) spongocoel (3) pseudocoel (4) haemocoel

Description : Animals having open circulatory system POSSESSES – (1) coelenteron (2) spongocoel (3) pseudocoel (4) haemocoel

Last Answer : (4) haemocoel Explanation: 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. The internal organs are suspended in a network of blood-filled sinuses or open spaces which collectively form the haemocoel.

The closed circulatory system is more efficient. Since blood circulates only inside blood vessels it can do it with more pressure reaching farther distances between the organs where hematosis happens and the peripheral tissues. In addition the circulatory speed also heightens making possible more oxygen supply to great consuming tissues, like the muscle tissues that then can perform faster movements. Animals with an open circulatory system (with the exception of insects that do gas exchange independently from the circulation) are generally slower and have a low metabolic rate.

A closed circulatory system is one in which blood circulates only inside blood vessels. For this reason the blood pressure is higher in animals with closed circulatory system. The cellularity of the blood is also higher with many specific blood cells. The closed circulatory system is a feature of annelids, cephalopod molluscs and vertebrates.

Last Answer : What are the advantages of the closed circulatory system over the open circulatory system?

In animals that do not present the circulatory system the transport of substances occurs by cell to cell diffusion. The blood is a fundamental means of substance transport for larger animals since in these animals there are tissues distant from each other and from the environment thus making diffusion impossible.
