Cardiovascular System Review

Front

What is the systemic circulation?

Back

The systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the left ventricle of the heart to the aorta and throughout the body, returning deoxygenated blood back to the right atrium.

Front

What is the pulmonary circulation?

Back

The pulmonary circulation is the part of the cardiovascular system that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation and then returns oxygenated blood to the left atrium.

Front

What is the function of the tricuspid AV valve?

Back

The tricuspid AV valve controls blood flow from the right atrium to the right ventricle, preventing backflow when the ventricle contracts.

Front

What is the function of the bicuspid (mitral) AV valve?

Back

The bicuspid (mitral) AV valve controls blood flow from the left atrium to the left ventricle, preventing backflow when the ventricle contracts.

Front

What is the role of the aortic semilunar valve?

Back

The aortic semilunar valve prevents backflow of blood from the aorta into the left ventricle after the ventricle has contracted.

Front

What is the role of the pulmonary semilunar valve?

Back

The pulmonary semilunar valve prevents backflow of blood from the pulmonary artery into the right ventricle after the ventricle has contracted.

Front

What type of blood returns to the heart from the lungs?

Back

Oxygenated blood returns to the heart from the lungs.

Front

What type of blood returns to the heart from the body?

Back

Deoxygenated blood returns to the heart from the body.

Front

What are pulmonary arteries?

Back

Pulmonary arteries are blood vessels that carry deoxygenated blood from the right ventricle of the heart to the lungs.

Front

What are pulmonary veins?

Back

Pulmonary veins are blood vessels that carry oxygenated blood from the lungs back to the left atrium of the heart.
