What is the functional difference between the four chambers of the heart?
(N/A) The heart consists of four chambers, each with a specific role in the circulatory system:
| Chamber | Function |
|---|---|
| $Right \text{ atrium}$ | Receives deoxygenated (impure) blood from the rest of the body via the $vena \text{ cava}$ and pumps it into the $right \text{ ventricle}$. |
| $Left \text{ atrium}$ | Receives oxygenated (pure) blood from the lungs via the $pulmonary \text{ vein}$ and pumps it into the $left \text{ ventricle}$. |
| $Right \text{ ventricle}$ | Receives deoxygenated blood from the $right \text{ atrium}$ and pumps it to the lungs for oxygenation via the $pulmonary \text{ artery}$. |
| $Left \text{ ventricle}$ | Receives oxygenated blood from the $left \text{ atrium}$ and pumps it to the entire body via the $AORTA$ (the main artery). |
