Capillaries

Tiny, thin-walled blood vessels that drop off oxygen and nutrients and pick up carbon dioxide or waste.

Ventricles

Myocardium

The thick middle layer of the heart responsible for contraction and pumping blood.

Epicardium

The outer layer of the heart that contains fluid to reduce friction.

Atrium

The upper chambers of the heart that receive blood returning from the veins.

Tricuspid valve

The valve located between the right atrium and right ventricle, consisting of three leaflets.

Mitral valve

The valve located between the left atrium and left ventricle, prevented blood from flowing back into the atrium, also called the bicuspid valve.

Aortic valve

The valve located between the left ventricle and the aorta, preventing blood from flowing back into the ventricle.
