Question

Describe Human circulatery system?

Answer 1

Hello mate,

Here is your answer,

Arteries carry oxygen-rich blood from the heart through the body. Veins carry oxygen-poor blood back to the heart.

The superior vena cava carries oxygen-poor blood into the heart. The aorta carries oxygenated blood from the heart to organs and tissues.

In the systemic circulation, the left ventricle pumps de-oxygenated blood into the pulmonary artery.

The blood, which is now low in oxygen, is pumped into the lungs for oxygenation.

now collected in the pulmonary vein and travels to the right atrium and into the right ventricle.

Aorta pumps oxygenated blood to all parts of the body.
