The stomach is a muscular sac that is important for absorbing food and preparing food for further digestion.
The internal oblique is a muscle of the abdomen. It is an intermediate muscle present under the external oblique and above the transverse abdominal muscle. The internal oblique functions as an antagonist to the diaphragm and helps in respiration. The internal oblique muscles are also termed as “same side rotators” and help achieve torsional movement of the trunk.
