Circulatory System Review

The purpose of the pulmonary circuit/loop (pulmonary circulation) is to:

• remove oxygen from oxygen-rich blood

• add oxygen to oxygen-rich blood

• add oxygen to oxygen-poor blood

• remove oxygen from oxygen-poor blood

Olivia and Benji are curious about the heart's structure. They learned that the two upper chambers of the heart that receive blood are called:

• atria (plural of atrium)

• ventricles

Blood is moved away from the right ventricle through the a blood vessel called the:

• pulmonary artery

• aorta

• superior vena cava

• coronary sinus

Which large blood vessels are responsible for carrying blood away from the heart?

• arteries

• capillaries

• veins

• venae cavae

Pulmonary circulation loop involves blood between the heart and the:

• body

• digestive organs

• brain

• lungs

Capillaries are where gases are exchanged between the blood & body.

• True

• False

What does letter D represent?

• Aorta

• Left Atrium

• Left ventricle

• Right Atrium

Select ALL statements that are true about veins:

• they typically carry oxygen-poor blood

• they typically carry oxygen-rich blood

• they carry blood from body back into the heart

• they contain valves to push blood back to heart

• they are where we can feel our pulse

Heart chamber that receives oxygen-rich blood from the lungs.

• left atrium

• right atrium

• left ventricle

• right ventricle

Imagine you're a young aspiring cardiologist. You're studying the heart's chambers and you come across a tricky question: Which chamber receives oxygen-poor blood from the vena cava?

• left atrium

• right atrium

• left ventricle

• right ventricle
