Answer:

1. Left Atrium

Description - One of the heart's upper chambers that plays a role in blood circulation.

Function - Receives oxygenated blood from the lungs and then empties into the left ventricle.

2. Left Ventricle

Description - The thickest of the heart's chambers and its cavity is circular in shape.

Function - Pumps the oxygenated blood to the whole body through the aorta.

3. Right Atrium

Description - One of the heart's upper chambers that plays a role in blood circulation.

Function - Collects deoxygenated blood and directs it to the right ventricle.

4. Right Ventricle

Description - Comprises a thin wall and its cavity is crescentic in shape compared to its counterpart.

Function - Pumps the deoxygenated blood to the lungs through the pulmonary artery.

5. Valves

Description - Valves are flaps (leaflets) and while normal valves have three flaps (leaflets), the mitral valve has two. There are four valves in the heart, namely, the Pulmonary Valve, the Tricuspid Valve, the Aortic Valve, and the Mitral Valve.

Function - Prevents the backward flow of blood and is designed to control the direction of blood flow through the heart, and acts as one-way inlets for blood coming into a ventricle and one-way outlets for blood leaving a ventricle.
