Difference between Abdomen and Abdominal Cavity

The abdomen and the abdominal cavity are two different body parts. The abdomen is the part of the body that houses the intestines, stomach, liver, and other organs. The abdominal cavity is the space inside of the abdomen. It houses these organs and also serves as a place for muscles to attach. The muscles in this area help with breathing and movement.

What is Abdomen?

  • Abdomen is the name for the section of the body below the ribcage and above the pelvis. This area contains a number of important organs, including the stomach, liver, and intestines. The abdomen is also where most of the body’s fluid waste is excreted.
  • Abdomen is often used interchangeably with belly or tummy, but these terms actually refer to a smaller portion of the abdomen. The belly is the soft, round area between the ribs and hipbones, while the tummy is located even lower, between the belly button and pubic bone.
  • When someone refers to having a “big stomach,” they generally mean that their waistline is larger than average. However, abdominal obesity can also refer to an excessive accumulation of fat around the organs in the abdomen.
  • This type of obesity is particularly dangerous, as it can lead to a number of health problems, including heart disease and diabetes. Abdominal obesity can be reduced through weight loss and exercise.

What is Abdominal Cavity?

The abdominal cavity is a large, hollow space in the abdomen that contains the stomach, small intestine, large intestine, liver, pancreas, spleen, and gallbladder. The abdominal cavity is lined with a thin layer of tissue called the peritoneum. The peritoneum helps to protect the organs in the abdominal cavity and prevents them from sticking together. Abdominal pain can occur when an organ in the abdominal cavity becomes inflamed or irritated. Abdominal pain can also be caused by a build-up of gas or stool in the intestine, or by constipation.

Difference between Abdomen and Abdominal Cavity

  • Abdomen is the area between the thorax and pelvis. Abdominal cavity is the space within the abdomen that contains the abdominal organs. The abdominal organs include the stomach, small intestine, large intestine, pancreas, spleen, and liver.
  • The abdominal cavity is divided into four regions: the right upper quadrant, left upper quadrant, right lower quadrant, and left lower quadrant. Abdominal pain can originate from any of the abdominal organs or structures.
  • Abdominal pain is often described as a crampy, achy feeling that may be sharp or stabbing. Abdominal pain can be acute (short-term) or chronic (long-term). If you have chronic abdominal pain, it may persist for weeks to months.
  • Abdominal pain can vary in intensity from mild to severe. Severe abdominal pain may be a sign of a life-threatening condition. If you have severe abdominal pain, seek medical attention immediately.


The abdomen is the muscular wall that separates the abdominal cavity from the thoracic cavity. The abdominal cavity is a space within the body that contains various organs, such as the stomach, small intestine, large intestine, liver, and pancreas. It’s important to understand these differences in order to accurately discuss anatomy and physiology.
