Blood Flow & Heart Parts Flashcard

Front

What is the function of the pulmonary valve?

Back

The pulmonary valve allows oxygen-depleted blood to flow from the right ventricle into the pulmonary artery, which carries it to the lungs for oxygenation.

Front

What type of blood does the pulmonary artery carry?

Back

The pulmonary artery carries oxygen-depleted (deoxygenated) blood from the heart to the lungs.

Front

What is the role of the aorta in the circulatory system?

Back

The aorta is the main artery that carries oxygen-rich blood from the left ventricle to the rest of the body.

Front

What is atrial fibrillation?

Back

Atrial fibrillation is a heart condition characterized by irregular and often rapid heart rate, leading to poor blood flow.

Front

What does pulmonary circulation refer to?

Back

Pulmonary circulation refers to the movement of blood between the heart and the lungs.

Front

Which chamber of the heart receives oxygen-poor blood from the body?

Back

The right atrium receives oxygen-poor blood from the body through the superior and inferior vena cavae.

Front

What is the function of the mitral valve?

Back

The mitral valve controls blood flow from the left atrium to the left ventricle, preventing backflow.

Front

What is the difference between oxygen-rich and oxygen-poor blood?

Back

Oxygen-rich blood is bright red and carries oxygen from the lungs to the body, while oxygen-poor blood is darker and carries carbon dioxide from the body back to the lungs.

Front

What is the role of the ventricles in the heart?

Back

The ventricles are the lower chambers of the heart that pump blood out of the heart: the right ventricle pumps to the lungs, and the left ventricle pumps to the body.

Front

What is the significance of the tricuspid valve?

Back

The tricuspid valve regulates blood flow from the right atrium to the right ventricle and prevents backflow into the atrium.
