Heart Anatomy and Function Quiz

Where are the atria located in the heart?

• Posterior end of the heart

• Anterior end of the heart

• Left side of the heart only

• Right side of the heart only

What is the function of the atria in the heart?

• Pump blood throughout the body

• Receive blood from the veins and force it into a ventricle

• Separate the left and right ventricles

• Generate pressure to fill the ventricles

What separates the left and right ventricles in the heart?

• Atrial septum

• Interventricular septum

• Pulmonary valve

• Mitral valve

Which chambers of the heart have a greater load due to pumping blood throughout the body and lungs?

• Atria

• Ventricles

• Left atrium

• Right atrium

What is the function of the atrio-ventricular valves in the heart?

• Control the flow of blood between the atria and ventricles

• Control the flow of blood out of the ventricles

• Control the flow of blood into the lungs

• Control the flow of blood into the liver

Which valves are included in the semilunar valves?

• Tricuspid and Bicuspid

• Aortic and Pulmonary Semilunar

• Mitral and Tricuspid

• Pulmonary and Mitral

What is the role of the semilunar valves in the heart?

• Control the flow of blood between the atria and ventricles

• Control the flow of blood out of the ventricles

• Control the flow of blood into the atria

• Control the flow of blood into the kidneys

What is the function of the aorta in the circulatory system?

• Carries blood from the heart to the lungs

• Returns oxygenated blood from the lungs to the heart

• Carries blood from the heart to all parts of the body except the lungs

• Brings deoxygenated blood from the body to the heart

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

• Aorta

• Pulmonary Vein

• Pulmonary Artery

• Venae Cavae

What is the role of the pulmonary artery in the circulatory system?

• Carries oxygenated blood to the body

• Returns deoxygenated blood to the heart

• Carries deoxygenated blood from the right ventricle to the lungs

• Returns oxygenated blood from the lungs to the heart
