What is the Pulmonary Artery?

Back

The Pulmonary Artery is the blood vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

Front

What is the Systemic Circuit?

Back

The Systemic Circuit is the pathway in which oxygenated blood is pumped from the left ventricle of the heart to the body and returns deoxygenated blood back to the heart.

Front

What is the Pulmonary Valve?

Back

The Pulmonary Valve is a valve located between the right ventricle and the pulmonary artery that prevents backflow of blood into the heart.

Front

What is the SA Node?

Back

The SA Node, or Sinoatrial Node, is the natural pacemaker of the heart that initiates the electrical impulses for heartbeats.

Front

What is unique about the Pulmonary Artery?

Back

The Pulmonary Artery is the only artery in the body that carries deoxygenated blood.

Front

What is the function of the heart's valves?

Back

The heart's valves ensure unidirectional blood flow through the heart chambers and prevent backflow.

Front

What is the role of the Aorta?

Back

The Aorta is the largest artery in the body that carries oxygenated blood from the left ventricle to the rest of the body.

Front

What is the difference between oxygenated and deoxygenated blood?

Back

Oxygenated blood is rich in oxygen and is carried from the lungs to the body, while deoxygenated blood is low in oxygen and is carried from the body to the lungs.

Front

What is the function of the right atrium?

Back

The right atrium receives deoxygenated blood from the body through the superior and inferior vena cavae.

Front

What is the role of the left ventricle?

Back

The left ventricle pumps oxygenated blood into the aorta to be distributed throughout the body.
