Understanding the Heart

Which chamber receives oxygen-rich blood from the lungs?

• Left atrium

• Right atrium

• Left ventricle

• Pulmonary artery

What is the function of the right atrium?

• The right atrium pumps blood to the aorta.

• The right atrium functions as a storage chamber for nutrients.

• The right atrium collects oxygenated blood from the lungs.

• The right atrium functions to collect deoxygenated blood and pump it into the right ventricle.

What are the four chambers of the heart?

• Right ventricle, left atrium, left ventricle, right atrium

• Right atrium, left ventricle, left atrium, right atrium

• Right atrium, right ventricle, left atrium, left ventricle

• Left atrium, left ventricle, right ventricle, right atrium

Which chamber pumps blood to the lungs?

• Right atrium

• Right ventricle

• Left atrium

• Left ventricle

What is the role of the left ventricle?

• The left ventricle receives deoxygenated blood from the body.

• The left ventricle pumps blood to the lungs for oxygenation.

• The left ventricle pumps oxygenated blood to the body.

• The left ventricle regulates blood pressure in the heart.

How many heart valves are there in the human heart?

• 5

• 3

• 2

• 4

What is the function of the tricuspid valve?

• To prevent blood from entering the left atrium.

• To regulate blood pressure in the pulmonary artery.

• To prevent backflow of blood from the right ventricle to the right atrium.

• To allow blood flow from the right atrium to the right ventricle.

Which valve prevents backflow into the left atrium?

• Aortic valve

• Tricuspid valve

• Pulmonary valve

• Mitral valve

What is the purpose of the pulmonary valve?

• To regulate oxygen levels in the blood.

• To allow blood flow from the right ventricle to the lungs.

• To pump blood into the left atrium.

• To prevent backflow of blood from the pulmonary artery into the right ventricle.

How does the aorta contribute to blood circulation?

• The aorta filters blood before it reaches the lungs.

• The aorta carries deoxygenated blood to the heart.

• The aorta is responsible for pumping blood into the heart.

• The aorta carries oxygenated blood from the heart to the body.
