The heart is a muscular organ located between the lungs that pumps oxygenated and deoxygenated blood throughout the body.

The heart has four chambers: the right atrium, right ventricle, left atrium, and left ventricle. Each chamber plays a specific role in the blood circulation process.

The atria are the receiving chambers of the heart. They collect blood returning from the body and lungs before transferring it to the ventricles.

The ventricles are the powerful pumping chambers. They receive blood from the atria and pump it out to the lungs and the rest of the body.

Valves are essential for preventing backflow of blood. They are located between the atria and ventricles and ensure blood flows in the correct direction.

The complete cycle of the heart pumping and filling with blood, taking roughly 0.8 seconds.

The muscular wall of the heart that contracts to pump blood.

The wall that separates the two ventricles of the heart.

The protective sac that surrounds the heart, reducing friction.

The circuit of blood flow that carries deoxygenated blood from the heart to the lungs.

The circuit of blood flow that carries oxygenated blood from the heart to the rest of the body.

The sound produced by the closing of the heart valves during the cardiac cycle.

The valve that controls the flow of blood between the right ventricle and the pulmonary artery, allowing deoxygenated blood to travel to the lungs.

The valve that controls the flow of blood between the left ventricle and the aorta, allowing oxygenated blood to travel to the rest of the body.

A large vein carrying deoxygenated blood from the lower body into the heart.

A large vein carrying deoxygenated blood from the head, arms, and upper body into the heart.

The chamber of the heart that receives deoxygenated blood from the superior and inferior vena cava.

The chamber of the heart that pumps deoxygenated blood to the lungs through the pulmonary valve.

The chamber of the heart that receives oxygenated blood from the lungs.

The chamber of the heart that pumps oxygenated blood to the body through the aortic valve.
