• The upper chambers of the heart

What is the role of the Pulmonary Artery?

• Carries oxygen-poor blood from the right side of your heart to your lungs

• Carries oxygenated blood from the lungs to the heart

• Main blood vessel through which oxygenated blood travels from the heart to organs throughout the body

What are Atriums?

• The upper chambers of the heart

• The lower chambers of the heart

• A condition in which the blood pressure in the arteries is consistently elevated above normal levels

• Commonly known as a heart attack, occurs when blood flow to the heart muscle is blocked, causing damage to the heart tissue

What is the function of the Pulmonary Vein?

What is the Aorta?

• Main blood vessel through which oxygenated blood travels from the heart to organs throughout the body

• The open space inside a blood vessel

What is the function of the Tricuspid Valve?

• Controls the flow of blood from the right upper chamber of the heart to the right lower chamber of the heart

• Carries deoxygenated blood from the heart to the lungs and returns oxygenated blood to the heart

• Pumps oxygenated blood throughout the body and returns deoxygenated blood back to the heart

What is the Pulmonary Circuit?

• Carries deoxygenated blood from the heart to the lungs and returns oxygenated blood to the heart

• Pumps oxygenated blood throughout the body and returns deoxygenated blood back to the heart

• The phase of the heartbeat when the heart contracts and pumps blood out
