The correct Answer is:
To answer the question "Dup sound is produced during closure of which of the following valves?", we can follow these steps: ### Step-by-Step Solution: 1. **Understand Heart Sounds**: The heart produces two main sounds, commonly referred to as "lub" and "dub." These sounds are associated with the closure of specific heart valves. 2. **Identify the First Heart Sound (Lub)**: The first heart sound (lub) is produced by the closure of the atrioventricular (AV) valves, which include: - Bicuspid (mitral) valve: located between the left atrium and left ventricle. - Tricuspid valve: located between the right atrium and right ventricle. 3. **Identify the Second Heart Sound (Dub)**: The second heart sound (dub) is produced by the closure of the semilunar valves, which include: - Aortic semilunar valve: located at the exit of the left ventricle into the aorta. - Pulmonary semilunar valve: located at the exit of the right ventricle into the pulmonary artery. 4. **Conclusion**: The "dup" sound is specifically produced during the closure of the semilunar valves (aortic and pulmonary valves). 5. **Final Answer**: Therefore, the correct answer to the question is that the "dup" sound is produced during the closure of the semilunar valves.
