The heart is a complex organ with distinct chambers that play crucial roles in its function. Understanding the structure of the heart can help in comprehending how it works.
Apex of the Heart
The apex of the heart is formed by the left ventricle. This chamber is responsible for pumping oxygenated blood to the rest of the body. The apex is the pointed end of the heart, located at the bottom, and it points downward, forward, and to the left.
Base of the Heart
The base of the heart is formed primarily by the left atrium, with a small contribution from the right atrium. The left atrium receives oxygenated blood from the lungs, while the right atrium receives deoxygenated blood from the body. The base is the broader, upper part of the heart, located at the top, and it faces upward, backward, and to the right.
In summary, the apex of the heart is formed by the left ventricle, and the base is formed by the left and right atria. These chambers work together to ensure the efficient circulation of blood throughout the body.
