HBS Respiratory and Cardiovascular System

Front

What is the function of the pulmonary artery?

Back

The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

Front

What is the role of the bicuspid (mitral) valve?

Back

The bicuspid (mitral) valve is located between the left atrium and left ventricle, preventing backflow of blood into the atrium during ventricular contraction.

Front

What are arteries?

Back

Arteries are blood vessels that carry blood away from the heart to various parts of the body.

Front

What type of blood does the pulmonary vein carry?

Back

The pulmonary vein carries oxygenated blood from the lungs back to the left atrium of the heart.

Front

What is the function of the tricuspid valve?

Back

The tricuspid valve prevents backflow of blood from the right ventricle into the right atrium during ventricular contraction.

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 heart, while deoxygenated blood is low in oxygen and is carried from the body back to the heart.

Front

What is the role of capillaries in the circulatory system?

Back

Capillaries are small blood vessels where the exchange of oxygen, carbon dioxide, nutrients, and waste occurs between blood and tissues.

Front

What is the significance of the aortic semilunar valve?

Back

The aortic semilunar valve prevents backflow of blood from the aorta into the left ventricle after the heart has contracted.

Front

What is the pathway of blood flow through the heart?

Back

Blood flows from the body into the right atrium, through the tricuspid valve to the right ventricle, then to the lungs via the pulmonary artery, back to the left atrium via the pulmonary vein, through the bicuspid valve to the left ventricle, and finally out to the body through the aorta.

Front

What is the function of veins?

Back

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