Atria: These are the two upper chambers of the heart.
The right atrium receives deoxygenated blood from the body through the veins,
while the left atrium receives oxygenated blood from the lungs through the pulmonary veins.
Ventricles: The two lower chambers of the heart are the ventricles.
The right ventricle pumps deoxygenated blood to the lungs for oxygenation,
while the left ventricle pumps oxygen-rich blood to the rest of the body.
Valves: The heart has four valves that regulate blood flow.
These are the tricuspid valve and pulmonary valve on the right side, and the mitral valve and aortic valve on the left side.
These valves ensure that blood flows in one direction through the heart.
Septum: The heart is divided into left and right halves by a muscular wall called the septum.
This prevents oxygen-rich and oxygen-poor blood from mixing.
