Options:
Answer:
Solution:
Semilunar valves are present at the opening of the pulmonary artery and the aorta to prevent the backflow of blood into the ventricles. Thus, (A) matches with (III).
Thebesian valve guards the opening of the coronary sinus into the right atrium. Thus, (B) matches with (I).
Eustachian valve guards the opening of the inferior vena cava into the right atrium. Thus, (C) matches with (IV).
Mitral valve, also known as the bicuspid valve, is located in the left atrioventricular (AV) aperture between the left atrium and the left ventricle. Thus, (D) matches with (II).
The correct matching is (A) - (III), (B) - (I), (C) - (IV), (D) - (II).
