Answer 2

Answer:

It's Simple

We Humans have a double circulatory system. This means that during a single cycle, the blood goes twice in the heart. There are two loops in which blood is circulated.The blood passes through the human heart two times to supply once to the whole body. So, it is called Double Circulation of blood.One loop is oxygenated and the other is de-oxygenated. This double circulatory system is important because it ensures provision of oxygenated blood to the muscle and not a mixture of oxygenated and de-oxygenated blood. Hence, this system ensures efficient supply of oxygenated blood to the muscles.
