The heart carries oxygen-rich blood.
The heart is a vital organ responsible for pumping blood throughout the body. It receives oxygen-rich blood from the lungs through the pulmonary veins and pumps it to the rest of the body through the aorta.
Here's how it works:
- Oxygen-poor blood from the body enters the right atrium of the heart.
- The right atrium pumps the blood into the right ventricle.
- The right ventricle pumps the blood to the lungs through the pulmonary arteries.
- In the lungs, the blood picks up oxygen and releases carbon dioxide.
- Oxygen-rich blood returns to the heart through the pulmonary veins.
- The oxygen-rich blood enters the left atrium of the heart.
- The left atrium pumps the blood into the left ventricle.
- The left ventricle pumps the blood to the rest of the body through the aorta.
This continuous cycle ensures that all the cells in the body receive the oxygen they need to function properly.
