Solution:
- Oxygen-rich blood from the lungs comes to the thin-walled upper chamber of the heart on the left, the left atrium.
- The heart has four chambers:- two atria and two ventricles.
- The 2 upper chambers are the Atria. They receive and collect blood.
- The 2 lower chambers are the Ventricles. They pump blood to other parts of your body.
- Arteries carry blood away from the heart (oxygen-rich blood) and veins carry blood to the heart (deoxygenated blood).
- The right atrium receives blood from the body which is deoxygenated or impure blood and is supplied by the veins.
- The right ventricle pumps the blood from the right atrium into the lungs to be oxygenated and removal of carbon dioxide.
- The left atrium receives blood from the lungs which are rich in oxygen (or oxygenated blood).
- The left ventricle pumps the blood from the left atrium out to the body, to supply the oxygenated blood to the entire body.
