Front

What are semilunar valves?

Back

Semilunar valves are the valves in the heart that allow blood to leave the heart and enter the arteries. They are located at the exit of the right ventricle (pulmonary valve) and the left ventricle (aortic valve).

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 cava and pumps it into the right ventricle.

Front

Which type of blood vessel has the largest diameter?

Back

Arteries have the largest diameter among blood vessels, allowing them to carry oxygenated blood away from the heart.

Front

What is the role of the superior and inferior vena cava?

Back

The superior and inferior vena cava are large veins that carry deoxygenated blood from the body back to the heart, specifically into the right atrium.

Front

Identify the left ventricle's function.

Back

The left ventricle pumps oxygenated blood into the aorta, which distributes it to the rest of the body.

Front

What is the difference between arteries and veins?

Back

Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood back to the heart.

Front

What is the significance of the pulmonary valve?

Back

The pulmonary valve prevents backflow of blood into the right ventricle after it has been pumped into the pulmonary artery.

Front

What is the role of the aortic valve?

Back

The aortic valve prevents backflow of blood into the left ventricle after it has been pumped into the aorta.

Front

What is deoxygenated blood?

Back

Deoxygenated blood is blood that has delivered its oxygen to the body's tissues and is returning to the heart to be re-oxygenated.

Front

What is the pathway of blood flow through the heart?

Back

Blood flows from the body into the right atrium, then to the right ventricle, into the lungs for oxygenation, back to the left atrium, into the left ventricle, and finally out to the body through the aorta.
