Answer 1

Answer:

In human beings, the blood goes through the heart twice during each cycle i.e. the blood passes through the human heart two times to supply once to the whole body. So, it is called Double Circulation of blood.

It is necessary for a human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system more efficient and helps in maintaining constant body temperature

Answer 2

Explanation:

Double Circulation

A circulatory path is a path taken by the blood, wherein it travels throughout the different organs of the body through arteries and veins. In humans, it is a closed circulatory system that exists, as blood flows in closed blood vessels. The circulatory system is responsible for the transport of gases, nutrients, waste products etc.
