Fully understanding the heart’s vital function in the body entails the need to first understand its anatomy. As a busy and hardworking organ, the heart needs to closely monitor all of its components to ensure proper functioning. Even a minor cardiac dysfunction may result in significant functional challenges in the total body function of an affecte...
The heart’s blood pumping cycle, which is called the cardiac cycle, begins when oxygen-free blood returns to the heart through the right atrium, after distributing oxygen and nutrients to other parts of the body. The blood then moves into the right ventricle, which facilitates a transfer of blood into the lungs. Within the lungs, all waste gases, s...
A normal heartbeat is evidence of the heart’s typical functioning, and each heartbeat is a manifestation of the oxygen-reloading process within the heart. As blood flows throughout the body in a single direction, any misdirection of the blood is avoided through the regulated closing and opening functions of the various cardiac chambers and valves. ...

The superior vena cava carries blood from your upper body. The inferior vena cava brings blood from your lower body. Then the right atrium pumps the blood to your right ventricle. Right ventricle: The lower right chamber pumps the oxygen-poor blood to your lungs through the pulmonary artery.
