Which of the following valves separates the atrial and ventricular chambers of the heart?
Pulmonary
Atrioventricular
Semilunar
Aortic
The Correct Answer is B
a. Pulmonary: The pulmonary valve separates the right ventricle from the pulmonary artery, which carries blood to the lungs.
b. Atrioventricular: The heart has four chambers: two upper atria and two lower ventricles. The atrioventricular valves (AV valves), also known as tricuspid and mitral valves, separate the atria from the ventricles and prevent blood from flowing backward from the ventricles to the atria.
c. Semilunar: Semilunar valves (aortic and pulmonary) are located at the base of the aorta and pulmonary artery, preventing blood from flowing back into the ventricles.
d. Aortic: The aortic valve separates the left ventricle from the aorta, the main artery carrying blood away from the heart to the body.
