Stomach and Abdomen Anatomy
The stomach and abdomen are two distinct parts of the body, but they are closely related. The stomach is located in the upper left part of the abdominal cavity and is responsible for breaking down food into small particles that can be absorbed by the body. The abdomen is the area between the chest and the pelvis and includes the organs of the digestive, urinary, and reproductive systems.
Anatomy is the study of the structure and function of the body and how its parts work together. The stomach and abdomen contain many organs that work together to form the digestive, urinary, and reproductive systems.
Stomach Anatomy and Function
The stomach is a hollow muscular organ located in the upper left portion of the abdominal cavity. It is responsible for breaking down food into small particles that can be absorbed by the body. The stomach is divided into four parts: the fundus, body, antrum, and pylorus.
The fundus is the uppermost portion of the stomach and is the main storage area for food. The body is the middle portion of the stomach and is responsible for breaking down food with digestive enzymes and acids. The antrum is the lowermost part of the stomach and is responsible for pushing the food into the small intestine. The pylorus is the opening between the stomach and small intestine and is responsible for controlling the release of food into the small intestine.
Abdomen Anatomy and Function
The abdomen is the area between the chest and the pelvis and includes the organs of the digestive, urinary, and reproductive systems. It is divided into four quadrants: the right upper, left upper, right lower, and left lower.
The right upper quadrant contains the liver, gallbladder, right kidney, and part of the small intestine. The left upper quadrant contains the stomach, spleen, left kidney, and part of the small intestine. The right lower quadrant contains the appendix, cecum, ascending colon, and part of the small intestine. The left lower quadrant contains the descending colon, sigmoid colon, rectum, and part of the small intestine.
The organs of the abdomen work together to digest, absorb, and eliminate food; produce and eliminate urine; and support reproductive functions.
