Understanding Heart Anatomy and Function

What is the primary function of the heart in the human body?

• To filter blood

• To pump blood throughout the body

• To produce red blood cells

• To store oxygen

Which chamber of the heart receives deoxygenated blood from the body?

• Left atrium

• Right atrium

• Left ventricle

• Right ventricle

What is the correct order of blood flow through the heart starting from the right atrium?

• Right atrium, right ventricle, pulmonary artery, lungs, left atrium, left ventricle, aorta

• Right atrium, left atrium, right ventricle, left ventricle, aorta, lungs

• Right atrium, left ventricle, right ventricle, left atrium, aorta, lungs

• Right atrium, right ventricle, left atrium, left ventricle, aorta, lungs

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

• Tricuspid valve

• Pulmonary valve

• Mitral valve

• Aortic valve

What is the role of the pulmonary valve?

• To prevent blood from flowing back into the right ventricle

• To prevent blood from flowing back into the left ventricle

• To prevent blood from flowing back into the right atrium

• To prevent blood from flowing back into the left atrium

What is the function of the tricuspid valve?

• To prevent blood from flowing back into the left ventricle

• To prevent blood from flowing back into the right atrium

• To prevent blood from flowing back into the left atrium

• To prevent blood from flowing back into the right ventricle

Which blood vessel carries oxygenated blood from the lungs to the heart?

• Pulmonary artery

• Pulmonary vein

• Aorta

• Superior vena cava
