Between left atrium and left ventricle ii. Between right ventricle and pulmonary artery iii. Between right atrium and right ventricle
Answer: (C) a-iii, b-i, c-ii. Answer: (c) a-iii, b-i, c-ii Solution: The tricuspid valve guards the opening between the right atrium and right ventricle (iii).
- A.a-i, b-ii, c-iii
- B.a-i, b-iii, c-ii
- C.a-iii, b-i, c-ii✓
- D.a-ii, b-i, c-iii
Correct Answer
(C) a-iii, b-i, c-ii
Solution & Explanation
Answer: (c) a-iii, b-i, c-ii Solution: The tricuspid valve guards the opening between the right atrium and right ventricle (iii). The bicuspid (mitral) valve guards the opening between the left atrium and left ventricle (i). The semilunar valves guard the openings of the ventricles into the pulmonary artery and aorta, e.g. right ventricle to pulmonary artery (ii). NCERT: Ch 15, p.198, line 19 — "the tricuspid valve, whereas a bicuspid or mitral valve guards the opening between the left atrium"
