Describe the circulation of blood in human beings.
Class 10(biology)

Answer 1

The heart is the key organ for blood circulation and the double circulation is an efficient way of circulation as it provides an effective way of circulation.

• The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body.

• It consists of the heart and the blood vessels running through the entire body.

• The arteries carry blood away from the heart; the veins carry it back to the heart.

• The system of blood vessels resembles a tree: The “trunk” – the main artery (aorta) – branches into large arteries, which lead to smaller and smaller vessels.

• The smallest arteries end in a network of tiny vessels known as the capillary network.
