Cardiovascular System Review

Front

What is the right ventricle?

Back

The right ventricle is one of the four chambers of the heart that pumps deoxygenated blood to the lungs for oxygenation.

Front

What is the function of the Atrioventricular Node (AV Node)?

Back

The AV Node is located in the septum and causes a delay in the electrical impulse, allowing the atria to contract before the ventricles.

Front

What is Tachycardia?

Back

Tachycardia is a condition characterized by an elevated heart rate, typically defined as a resting heart rate over 100 beats per minute.

Front

What is Erythroblastosis Fetalis?

Back

Erythroblastosis Fetalis is a condition that can occur when an Rh-negative mother has a second Rh-positive child, leading to the mother's immune system attacking the baby's red blood cells.

Front

What are veins?

Back

Veins are blood vessels that carry deoxygenated blood back to the heart.

Front

What is the role of the left atrium?

Back

The left atrium receives oxygenated blood from the lungs through the pulmonary veins.

Front

What is the sinoatrial node (SA Node)?

Back

The SA Node is the natural pacemaker of the heart, initiating the electrical impulses that regulate heartbeats.

Front

What is bradycardia?

Back

Bradycardia is a condition characterized by a slower than normal heart rate, typically defined as a resting heart rate below 60 beats per minute.

Front

What is the function of arteries?

Back

Arteries are blood vessels that carry oxygenated blood away from the heart to the body's tissues.

Front

What is diastole?

Back

Diastole is the phase of the cardiac cycle when the heart muscle relaxes and the chambers fill with blood.
