Physiological sounds are the noises produced by the body's internal processes. These sounds can include heartbeats, breathing, and digestive noises. They are often used in medical settings to assess health, as changes in these sounds can indicate various conditions. For example, a doctor may listen to a patient's heart with a stethoscope to detect irregular rhythms. These sounds are generated by the movement of air, blood, and other fluids within the body. Each sound has a specific origin; for instance, breath sounds come from the lungs, while bowel sounds result from the movement of food through the intestines. Understanding these sounds is essential for diagnosing and monitoring health.
