Palpation of the epigastrium can be used to feel the structures below it. [2] This includes the liver, and the stomach. [2] An aortic aneurysm may be felt as a mass in the epigastrium. [3] Stomach sounds may be heard when auscultating (using a stethoscope) on the epigastrium. [2]
The upper limit is the umbilicus while the pubis bone constitutes its lower limit. The lateral boundaries are formed are drawing straight lines through the midway between the anterior superior iliac spine and symphisis pubis .
It contains a serous fluid called peritoneal fluid that allows motion. This motion is apparent of the gastrointestinal tract. The peritoneum, by virtue of its connection to the two (parietal and visceral) portions, gives support to the abdominal organs. The peritoneum divides the cavity into numerous compartments.
The abdomen (colloquially called the gut, belly, tummy, midriff, tucky, or stomach [citation needed]) is the front part of the torso between the thorax (chest) and pelvis in humans and in other vertebrates. The area occupied by the abdomen is called the abdominal cavity.

They are made of a bone-like material called dentin, which is covered by the hardest tissue in the body—enamel. [8] Teeth have different shapes to deal with different aspects of mastication employed in tearing and chewing pieces of food into smaller and smaller pieces. This results in a much larger surface area for the action of digestive ...
The structures within the intraperitoneal space are called "intraperitoneal" (e.g., the stomach and intestines), the structures in the abdominal cavity that are located behind the intraperitoneal space are called "retroperitoneal" (e.g., the kidneys), and those structures below the intraperitoneal space are called "subperitoneal" or ...
The coordinated contractions of these layers is called peristalsis and propels the food through the tract. Food in the GI tract is called a bolus (ball of food) from the mouth down to the stomach. After the stomach, the food is partially digested and semi-liquid, and is referred to as chyme. In the large intestine the remaining semi-solid ...
