How does blood circulation take place in humans?
Answers
Answer:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.
Answer:
With a vast network of arteries ,veins and capillaries .Check out google for images you will be amazed . Heart pumps blood . Blood enters heart by 2 major veins superior vena cava and inferior vena cava ,then undergoes pulmonary circulation returns back to left ventricle of heart from where the ventricles of your heart contract and pumps blood through aorta . aorta divides into various arteries which move blood to you limbs and abdomen ,legs ,brain . The arteries will further divide in very fine (hair like )arterioles which will provide nutrients and oxygen to cells via diffusion . The arterioles are attached to veinlets which will take away the impure ( deoxygenated ) blood . veinlets will fuse to form veins and the veins will open into the vena cava and the process continues .
