• To produce blood cells

• To absorb nutrients from digested food

What separates the right side of the heart from the left side?

• A muscular valve

• A solid wall

• A layer of pericardial fluid

• A series of blood vessels

What prevents the blood on the right side of the heart from coming into contact with the blood on the left side?

• Aorta Superior

• Septum

• Tricuspid valve

• Right pulmonary artery

Which valve is also known as the main valve in the heart?

• Tricuspid valve

• Pulmonary (semi-lunar) valve

• Bicuspid valve

What is the name of the large vein that brings deoxygenated blood from the body to the heart?

• Aorta Superior

• Right pulmonary veins

Which of the following carries oxygenated blood away from the heart?

What is the function of the right atrium and right ventricle in the heart?

• They supply blood to the body at high pressure.

• They supply blood to the lungs at low pressure.

• They receive blood from the lungs at high pressure.

• They receive blood from the body at low pressure.

When the chambers of the left side of the heart are full, what action does the heart take?

• The heart relaxes and allows blood to flow back into the lungs.

• It contracts simultaneously with the right side, acting as a high-pressure pump.

• The left side of the heart pumps blood to the pulmonary artery.

• The heart stops momentarily before pumping blood.

What is the role of the left side of the heart in the circulatory system?

• It supplies oxygenated blood to the lungs.

• It receives deoxygenated blood from the body tissues.

• It supplies oxygenated blood to the body tissues such as muscle cells.

• It pumps deoxygenated blood to the pulmonary vein.
