Blood Flow of Heart

What part of the heart delivers deoxygenated blood to the lungs?

• Pulmonary artery

• Pulmonary Vein

• Aorta

• Left Ventricle

What part of the heart delivers richly oxygenated blood to the body?

• Tricuspid Valve

• Superior Vena Cava

• Aorta

• Pulmonary Artery

Blood flows in the following sequence in the heart: Superior vena cava/Inferior vena cava, right atrium, tricuspid valve, right ventricle, pulmonic valve, pulmonary artery, lungs, pulmonary vein, left atrium, bicuspid valve, left ventricle, aortic valve, aorta

• True

• False

On the right side of the heart, blood flows from the right ventricle to the _____?

• Tricuspid valve to the pulmonary vein

• Pulmonic valve to the pulmonary artery

• Tricuspid valve to pulmonary artery

• Inferior vena cava to the aorta

Which of the following valves is located between the right atrium and right ventricle?

• Aortic valve

• Mitral valve

• Tricuspid valve

• Pulmonary valve

Answer explanation

The tricuspid valve is located between the right atrium and right ventricle, allowing blood to flow from the atrium to the ventricle. The aortic and pulmonary valves are located in the left side of the heart, while the mitral valve is between the left atrium and ventricle.

blood flow is measured in

• mm/hg

• ml/min

• beats/min

• mm/min

Which valve prevents the backflow of blood from the left ventricle to the left atrium?

• Tricuspid valve

• Pulmonary valve

• Mitral valve

• Aortic valve

Answer explanation

The mitral valve, also known as the bicuspid valve, is located between the left atrium and left ventricle. It prevents the backflow of blood into the left atrium when the left ventricle contracts.

The blood enters on the left side of the heart through the ______________ and enters the left atrium. It then passes through the _____________to enter the left ventricle.*

• pulmonary artery, mitral valve

• pulmonary vein, tricuspid valve

• pulmonary artery, aortic valve

• pulmonary vein, bicuspid valve

The atriums are located below the ventricles.

• True

• False

The bicuspid valve is located on the left side of the heart.

• True

• False
