The document outlines the key parts of the heart including chambers, valves, and vessels. It describes the septum separating the right and left sides, with the atria on top and ventricles below. The right side carries deoxygenated blood from the vena cava into the right atrium and ventricle through the tricuspid valve, then into the pulmonary artery through the pulmonary valve. The left side carries oxygenated blood from the pulmonary veins into the left atrium and ventricle through the bicuspid valve, then into the aorta through the aortic valve.

2. (1) The Basics
• Septum:
Piece of meat separating the right and left side.
• Atria = Chambers on the top
• Ventricles = Chambers near the bottom
3. (2) The Right Side
--CARRIES DEOXYGENATED BLOOD-• Superior / Inferior Vena Cava:
Empties into the right atrium.
• Tricuspid Valve:
The valve between the right atrium + ventricle.
• Pulmonary Semilunar Valve:
The valve between the right ventricle + pulmonary
artery.
• Pulmonary Artery:
Exits the right ventricle.
4. (3) The Left Side
--CARRIES OXYGENATED BLOOD-• Pulmonary Veins:
Empties into the left atrium.
• Bicuspid/Mitral Valve:
The valve between the left atrium + ventricle.
• Aortic Semilunar Valve:
The valve between the left ventricle + artery.
• Aorta:
Exits the left ventricle.
