Circulatory System Overview

These flashcards cover the key components and processes of the circulatory system as outlined in the lecture notes.

Deoxygenated Blood

Blood that has delivered its oxygen to the body tissues and is returning to the heart.

Right Atrium

The chamber of the heart that receives deoxygenated blood from the body.

Tricuspid Valve

The valve that allows blood to flow from the right atrium to the right ventricle.

Right Ventricle

The chamber of the heart that pumps deoxygenated blood to the pulmonary arteries.

Pulmonary Semilunar Valve

The valve that controls blood flow from the right ventricle into the pulmonary arteries.

Pulmonary Arteries

Blood vessels that carry deoxygenated blood from the heart to the lungs.

Pulmonary Veins

Blood vessels that carry oxygenated blood from the lungs back to the heart.

Left Atrium

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

Mitral Valve

The valve that allows blood to flow from the left atrium to the left ventricle.

Left Ventricle

The chamber of the heart that pumps oxygenated blood into the aorta.

Aortic Valve

The valve that controls blood flow from the left ventricle into the aorta.

Aorta

The largest artery in the body that distributes oxygenated blood to the body tissues.

Capillaries

Small blood vessels where the exchange of oxygen and carbon dioxide occurs.

Inferior and Superior Vena Cavae

Major veins that drain deoxygenated blood back into the right atrium.
