How Blood Circulation Works

Blood circulation is the continuous movement of blood through the heart, lungs,

and blood vessels. The heart acts as a pump, sending oxygen-poor blood to the lungs,

where it releases carbon dioxide and picks up oxygen. Oxygen-rich blood then returns to

the heart and is pumped to the rest of the body through arteries. Capillaries allow

oxygen and nutrients to reach cells, while veins carry waste-filled blood back to the heart.

This process helps maintain body temperature, fight infections, deliver hormones, and keep organs

functioning properly. Proper circulation supports energy levels, brain activity,

healing, and overall health every day daily.
