Why is blood circulation in human heart called double circulation?
Answers (1)
Ans.
In humans, blood passes through the heart twice during one complete cardiac cycle of the body. Once through the right ventricle to the left auricle of the heart, called pulmonary circulation. Second through the left ventricle to right auricle of the heart through body tissues, called systemic circulation.
Advantages of double circulation:
- Maintains higher blood pressure
- Allows greater flow of blood to the tissues.
- Creates more pressure to pump blood to other organs.
- Produces a large amount of energy to maintain life processes.
