The primary function of the heart is to circulate blood to and from tissues throughout the body. This process is essential for maintaining homeostasis and supporting vital functions. The heart acts as a pump, driving blood into the arteries, which transport oxygen-rich blood to the tissues. Once the tissues use the oxygen and nutrients from the blood, they return deoxygenated blood back to the heart through the veins.

By circulating blood, the heart facilitates the delivery of nutrients and oxygen to cells while also enabling the removal of waste products, including carbon dioxide. Although supplying nutrients, removing waste, and supplying oxygen are important processes that rely on the heart's function, these aspects are not the heart's primary role. Instead, they are outcomes of the heart's main task of blood circulation, highlighting the heart's crucial role in sustaining life and health.
