Q.Enumerate the uses of Stethoscope.

A stethoscope is a medical instrument used for auscultation — listening to internal body sounds such as the heartbeat, breathing, and intestinal activity — and is also used with a sphygmomanometer to measure blood pressure.

The stethoscope is one of the most familiar basic medical instruments, consisting of a chest piece (diaphragm/bell) that picks up sound, connected via flexible tubing to earpieces for the examiner. Its main uses are:

1. Listening to heart sounds — a doctor places the chest piece over the chest to hear the normal "lub-dub" heart sounds, and to detect abnormal sounds such as murmurs (caused by faulty valves or turbulent blood flow) or irregular rhythms (arrhythmias).

2. Listening to breath (lung) sounds — placed on the chest/back to check normal breathing sounds and to detect abnormalities such as wheezing, crackles, or reduced air entry, which can indicate conditions like asthma, pneumonia, or fluid in the lungs.

3. Listening to bowel (intestinal) sounds — placed on the abdomen to check normal peristaltic (gut movement) sounds, helping detect blockages or reduced gut activity.
