Front

What is the function of the Superior Vena Cava?

Back

The Superior Vena Cava carries deoxygenated blood from the upper body to the right atrium of the heart.

Front

What is the function of the Inferior Vena Cava?

Back

The Inferior Vena Cava brings deoxygenated blood from the lower body to the right atrium of the heart.

Front

Where are the atria located in relation to the ventricles?

Back

The atria are located above the ventricles.

Front

Which chamber of the heart is the most muscular?

Back

The left ventricle is the most muscular chamber of the heart.

Front

What is the sequence of blood flow through the heart?

Back

Blood flows from the Superior/Inferior Vena Cava to the right atrium, tricuspid valve, right ventricle, pulmonic valve, pulmonary artery, lungs, pulmonary vein, left atrium, bicuspid valve, left ventricle, aortic valve, and aorta.

Front

What is the role of the tricuspid valve?

Back

The tricuspid valve prevents backflow of blood from the right ventricle to the right atrium.

Front

What is the role of the bicuspid (mitral) valve?

Back

The bicuspid valve prevents backflow of blood from the left ventricle to the left atrium.

Front

What type of blood do the pulmonary veins carry?

Back

The pulmonary veins carry oxygenated blood from the lungs to the left atrium.

Front

What type of blood do the pulmonary arteries carry?

Back

The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.

Front

What is the purpose of the aortic valve?

Back

The aortic valve prevents backflow of blood from the aorta into the left ventricle.
