Q45 / 230 · NTA Abhyas (NEET) 2020 · Zoology · Body Fluids and Circulation
The correct arrangement of cardiac valves from the right side to the left sides is
- Abicuspid valve - pulmonary semilunar valve - aortic semilunar valve - tricuspid valve
- Btricuspid valve - aortic semilunar valve - pulmonary semilunar valve - bicuspid valve
- Ctricuspid valve - bicuspid valve - pulmonary semilunar valve - aortic semilunar valve
- Correct answerDtricuspid valve - pulmonary semilunar valve - aortic semilunar valve - bicuspid valve
Solution
The valve present on the extreme right is the right atrioventricular valve also called the tricuspid valve it has three cusps. Just besides this valve, the right ventricle opens into the pulmonary trun and this opening is guarded by a pulmonary semilunar valve. To the left of this valve, the left semilunar valve guards the opening between left ventricle and aorta. The valve present on the extreme left is the left atrioventricular valve also called the bicuspid valve it has two cusps.
Hence, the correct answer is option: 'D'.
