Auscultation is a check-up administered in your abdomen by using a stethoscope to listen to bowel sounds. When you hear bowel sounds, then your systems are perfectly normal. When there are areas that do not produce any grumbling noises, then there must be blockage in that area.
Let's examine the area for auscultation. The diagram is shown in the picture. The abdomen is divided into four quadrants. The upper boundary is the latissimus dorsi which is the group of muscles behind the arm and stretches to the side.
