Heart Structures and their Functions

Large blood vessels that carry blood away from the heart are called:

• arteries
• capillaries
• veins
• venae cavae

When the ventricles contract, the bicuspid (mitral) valve prevents blood from flowing from the ________.

• right ventricle to right atrium
• left ventricle to left atrium
• left atrium to the right atrium
• right atrium to the left atrium

The ______ bring the blood to and from the lungs (so that the blood becomes oxygenated before it leaves the heart).

• pulmonary arteries / pulmonary veins

• inferior vena cava / superior vena cava

• aortic arch / descending aorta

Blood vessels that supply the cardiac muscle of the heart with the oxygen and nutrients that they need.

• vena cava

• descending aorta

• coronary arteries

• pulmonary arteries

Which of these is found between the right atrium and the right ventricle?

• Bicuspid Valve (aka Mitral Valve)

• Tricuspid Valve

• Aortic (Semilunar valve)

• Pulmonary (Semilunar valve)

What is the purpose of the valves inside the heart?

• to pump the blood into the atria

• to prevent back-flow of blood from the atria to the ventricles

• to pump the blood into the ventricles

• to prevent back-flow of blood from the ventricles to the atria

Which of these is the correct order of the movement of blood after it leaves the heart?

• Aorta; Around the body; Vena cava; Right atrium; Right ventricle; Pulmonary arteries; Lungs; Pulmonary veins; Left atrium; Left ventricle

• Aorta; Around the body; Vena cava; Left atrium; Left ventricle; Pulmonary arteries; Lungs; Pulmonary veins; Right atrium; Right ventricle

• Aorta; Around the body; Vena cava; Right atrium; Right ventricle; Pulmonary veins; Lungs; Pulmonary arteries; Left atrium; Left ventricle

• Aorta; Around the body; Vena cava; Left atrium; Left ventricle; Pulmonary veins; Lungs; Pulmonary arteries; Right atrium; Right ventricle
