The heart and its structure

The heart contains how many chambers?

• 3

• 4

• 5

• 6

Which of the chambers are the pumping chambers

• Atrium

• Ventricle

Which of the chambers are the receiving chambers?

• Ventricles

• Atrium

• Valves

• Vessels

Why is the left ventricle bigger than the right ventricle?

• It has to pump to the arms

• It has to pump to the head

• It has to pump to the legs and feet

• It has to pump to the lungs

The left ventricle pumps what type of blood and to where

• Oxygenated to the lungs

• Deoxygenated to the lungs

• Oxygenated to the body

• Deoxygenated to the lungs

The pulmonary artery carries what type of blood to where?

• Deoxygenated blood to the lungs

• Deoxygenated blood to the heart

• Oxygenated blood to the lungs

• Oxygenated blood to the heart

The role of the valves are to

• Prevent back flow of blood

• Pump blood out of the heart

• To make sure blood flows in one direction

• Supply the lungs with blood

The tricuspid valve performs it s role where in the heart

• Between the left ventricle and right ventricle

• Between the right atrium and right ventricle

• Between the left ventricle and aorta

• Between the right ventricle and pulmonary artery

The bicuspid valve performs what role

• Prevent back flow of blood between the right atrium and left ventricle

• Prevent back flow of blood between the right ventricle and left ventricle

• Prevent back flow of blood between the left atrium and left ventricle

• Prevent back flow of blood between the right ventricle and the pulmonary veins.

The Aortic valve ensures oxygenated blood travels through the

• Vena cava

• Pulmonary vein

• Pulmonary Artery

• Aorta
