• Pumping blood throughout the body

• Collecting vessels at the top of the heart

• Allowing blood to travel in only one direction

• Dividing the heart into two pumps

What is the function of the valves in the heart?

• Pumping blood throughout the body

• Collecting vessels at the top of the heart

• Allowing blood to travel in only one direction

• Dividing the heart into two pumps

What is the septum in the heart?

• A muscular wall that divides the heart into two pumps

• A vessel that collects blood at the top of the heart

• A valve that prevents backflow of blood

• A vein that carries oxygen-rich blood to the heart

What is the role of the superior vena cava?

• Transporting oxygen-rich blood from the lungs to the heart

• Returning deoxygenated blood to the heart from the head and arms

• Carrying oxygen-poor blood from the heart to the lungs

• Dividing the heart into two pumps

What is the function of the inferior vena cava?

• Transporting oxygen-rich blood from the lungs to the heart

• Returning deoxygenated blood to the heart from the head and arms

• Transporting almost all venous blood from the abdomen and lower extremities back to the heart

• Dividing the heart into two pumps

What do the pulmonary arteries do?
