The human abdomen is divided into quadrants and regions by anatomists and physicians for the purposes of study, diagnosis, and treatment. [1] [2] The division into four quadrants allows the localisation of pain and tenderness, scars, lumps, and other items of interest, narrowing in on which organs and tissues may be involved.

They are located on the lateral sides of the abdominal wall respectively, inferior to (below) the thoracic cage, being separated by the epigastrium. [1] [2] The liver is in the right hypochondrium, extending through the epigastrium and reaching the left hypochondrium. The spleen and some of the stomach are in the left hypochondrium. [3]
The lower portion is the pelvic cavity, and it contains the urinary bladder, the rest of the large intestine (the lower portion), and the internal reproductive organs. [2] [3] There is no membrane that separates out the abdominal cavity from the pelvic cavity, so the terms abdominal pelvis and peritoneal cavity are sometimes used.
The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body cavity enclosed by the abdominal muscles, at the front and to the sides, and by part of the vertebral column at the back. Lower ribs can also enclose ventral and lateral walls. The abdominal ...
The abdominal cavity is a large body cavity in humans [1] and many other animals that contain organs. It is a part of the abdominopelvic cavity . [ 2 ] It is located below the thoracic cavity , and above the pelvic cavity .
In anatomy, the abdominal wall represents the boundaries of the abdominal cavity.The abdominal wall is split into the anterolateral and posterior walls. [1]There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum ...
The abdomen may be divided into four quadrants, more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersect at the patient's umbilicus (navel). [1] The right upper quadrant (RUQ) includes the lower right ribs, right side of the liver, and right side of the transverse colon.
