Difference between abdomen and stomach
Abdomen vs stomach:
It is extremely common that one may use the terms abdomen and stomach interchangeably and some even consider them as synonyms for each other. Yet, while the abdomen and the stomach are located in the near enough regions of the body, these two body parts are two different things which function separately as two different entities.
What is the abdomen?
The abdomen can be termed as the area of the body that is located in between the thorax and the pelvis. It would include the abdominal cavity, the organs, the muscles, skin, fat, etc. the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. From the exterior, the abdomen is covered by the skin and in the vertebrates area it is covered by the skeletal muscles and the sub-cutaneous fat layer which helps maintain the body heat for metabolic activities by acting as an insulator. Most of the digestion process occurs here as it is here that most of the alimentary tract is placed. Other important organs that are found inside the abdomen include the lower esophagus, the stomach, the duodenum, the jejunum, ileum, the cecum and the appendix, the ascending, transverse, descending colons, the liver, the kidneys, the pancreas, the spleen, the sigmoid colon and the rectum.
What is the stomach?
The term stomach, which is derived from the Latin term stomachus which is once again derived from the Greek word stomachos indicates the meaning of a reservoir of food which probably explains its purpose. The stomach can be found located inside the abdominal cavity which is once again located inside the abdomen. It is considered as a vital part of the digestion procedure and is quite hollow, muscular and sac-like in nature. It is located in between the oesophagus and duodenum of the alimentary tract and is known to secret protein digesting enzymes which can be quite strong in nature. When empty, the stomach contains acids and air and the acidity of the stomach when empty can lead to gastritis in individuals as well.
What is the difference between the abdomen and the stomach?
While the area that is referred to as the abdomen is found in between the thorax and the pelvis, the stomach can be found inside the abdominal cavity which is once again found inside the abdomen. Therefore, the abdomen refers to the larger area of the body whereas the stomach indicates a smaller organ which is housed in the abdominal cavity.
The term Abdomen is derived from the Latin word “abdodere” which indicates to hide which probably indicates its function as well which is hiding or protecting the vital and sensitive organs of the body. The term stomach is derived from the Latin term stomachus, which is once again derived from the Greek word stomachos, which means a reservoir of food which explains the function of the stomach as well- the place where the food is stored while the digestion process commences.
Whereas most of the digestive processes take place in the abdomen, the stomach serves a specific purpose. Because of the secretion of various acids and enzymes, the stomach is a very acidic place which is designed in such a way that these acids and enzyme would help break the large food in to molecules and help the body in absorbing the necessary nutrients from the food that has been consumed.
Also, while the abdomen contains most of the alimentary tract including the stomach, the stomach mainly contains gas or air, pyloric walls, connectors with esophagus, the first part of the duodenum etc which indicates that the abdomen contains a larger amount of organs in the body within its sphere.
