The heart pump is a muscular organ that circulates blood throughout the body. It beats approximately 60 to 100 times per minute, propelling oxygen-rich blood to every cell and then circulating deoxygenated blood back to the lungs for replenishment.
Here's a breakdown of the heart's role as a pump:
-
Function: The primary function of the heart is to pump blood, ensuring oxygen and nutrients reach all parts of the body while removing waste products.
-
The Process:
- The heart receives deoxygenated blood from the body.
- It pumps this blood to the lungs where it picks up oxygen.
- The oxygenated blood then returns to the heart.
- Finally, the heart pumps the oxygenated blood out to the rest of the body.
-
Beating: The rhythmic contraction and relaxation of the heart muscle, known as the heartbeat, is what drives this pumping action. The rate at which the heart beats is influenced by factors such as physical activity, stress, and overall health.
In short, the heart's role as a pump is essential for life, providing the necessary circulation to keep all bodily functions operating.
