Q. What are the merits of the closed circulatory system over the open circulatory system?

The closed circulatory system is more resourceful since blood circulates only inside blood vessels it can do it with more pressure reaching beyond distances between the organs where the peripheral tissues and hematosis happen. Additionally 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 usually slower and have a low metabolic rate.
