Explanation:

• For question 75: A stethoscope is used to listen to heart sounds, which are related to the functioning of heart valves. The pulmonary valve is one of the heart valves, and its sounds can be heard with a stethoscope. Electrical impulses are detected by an electrocardiogram (ECG), blood pressure is measured with a sphygmomanometer, and coronary thrombosis is a condition diagnosed through various tests like angiography rather than just listening with a stethoscope.

Answer:

1. pulmonary valve
2. dust
