Where does blood first enter the heart?

• Right ventricle

• Right atrium

• Left ventricle

• Left atrium

What blood vessel brings blood back to the heart from the body tissues?

• Aorta

• Inferior & Superior Vena Cava

• Coronary Sinus

• Coronary Arteries

After leaving the left atrium, what does the blood pass through before entering the left ventricle?

• Aortic Valve

• Pulmonary Valve

• Tricuspid Valve

• Mitral or Bicuspid Valve

What does the left ventricle do?

• pumps oxygen-rich blood to the rest of the body

• receives oxygen-rich blood from the lungs

• pumps oxygen-poor blood to the lungs

• receives oxygen-poor blood from the body

As blood is leaving the right atrium and entering the right ventricle, what valve does it pass through?

• Aortic valve

• Pulmonary valve

• Tricuspid valve

• Mitral or Bicuspid valve

As blood leaves the right ventricle, what does it pass through?

• Aortic valve

• Pulmonary valve

• Tricuspid valve

• Mitral or Bicuspid valve

What is the function of the left atrium?

• to pump oxygen-rich blood to all the tissues of the body

• to receive oxygen-rich blood from the lungs

• to pump oxygen-poor blood to the lungs

• to receive oxygen-poor blood from all the body tissues

After passing through the aortic valve, where is the blood now located?

• Aorta

• Inferior vena cava

• Superior vena cava

• Pulmonary veins

What does the right ventricle do?

• it pumps oxygen-rich blood to the body tissues

• it receives oxygen-rich blood from the lungs

• it pumps oxygen-poor blood to the lungs

• it receives oxygen-poor blood from the body tissues

After blood passes through the pulmonary valve, where is it located?

• Aorta

• Pulmonary veins
