The heart is a vital organ that acts as the body's pump, circulating blood throughout the body and delivering oxygen while removing waste products like carbon dioxide. It's made up of four chambers, each with valves that control blood flow.
Here are some key functions of the heart:
- Pumps blood throughout the body: The heart rhythmically contracts and relaxes to push blood through the circulatory system.
- Delivers oxygen to the body: Oxygen-rich blood from the lungs is pumped to the rest of the body, supplying cells with the oxygen they need to function.
- Removes waste products: The heart pumps carbon dioxide and other waste products from the body back to the lungs to be expelled.
The heart is a crucial component of our circulatory system, ensuring that our bodies receive the essential nutrients and oxygen needed to thrive.
