What is the difference between abdomen and stomach

It is sac like in appearance having acids that help digest the food being eaten. The acid is so acidic that large foods can be decomposed easily. With the aid of other digestive enzymes, the stomach is able to effectively break down food so that it can be absorbed by the body. The stomach is situated between the intestines and the esophagus. It is connected to the esophagus through the gastroesophageal sphincter which is responsible in containing the food that goes into the stomach.

This prevents the food from being propelled upwards as in the case of gastric reflux. At its terminal end, the stomach is connected to the duodenum first part of the small intestine through the pyloric sphincter.

Food that has already been digested by the stomach acids and enzymes will go the small intestine for final digestion through this sphincter.

Certain internal triggers stimulate the sphincter to open up and empty the partially digested food into the small intestine. The abdomen is a region of the body situated between the chest and pelvic area while the stomach is an organ of digestion. The human stomach is a muscular, elastic, J-shaped bag, lying crosswise in the abdominal cavity beneath the diaphragm. It changes size and shape according to is position of the body and the amount of food inside. It is about 12 inches The stomach's capacity is about 1 qt 0.

But the size changes with the food inside, the human stomach can produce and secrete about 2 to 3 liters of gastric acid per day with basal secretion levels being typically highest in the evening. It is surrounded by parasympathetic stimulant and orthosympathetic inhibitor plexuses anterior gastric, posterior, superior and inferior, celiac and myenteric , which regulate both the secretory activity and the motor activity of the muscles. The abdomen contains most of the tubelike organs of the digestive tract, as well as several solid organs.

Liver, is attached with gallbladder , and the pancreas all function in close association with the digestive tract and communicate with it via ducts. The spleens , kidneys, are also part of the abdomen, along with many blood vessels.

The abdomen contains an extensive membrane called the peritonenium. Hollow abdominal organs include the stomach, the small intestine, and the colon with its attached appendix. The spleen, kidneys, and adrenal glands also lie within the abdomen, along with many blood vessels including the aorta and inferior vena cava. Anatomists may consider the urinary bladder, uterus , fallopian tubes , and ovaries as either abdominal organs or as pelvic organs. The abdomen contains an extensive membrane called the peritoneum.

Cardia is where the contents of the esopahgus are emptied in the stoamch while Fundus is the upper curvature of the stomach. Corpus forms the central region and Antrum is the lower section that helps in emptying the contents in the small intestine. The importance of the abdominal cavity is that it is the largest space inside the body. A very thin layer of cells known as the peritoneum covers the abdominal cavity, and which is a very protective layer.

There are many organs suspended inside the abdominal cavity including the stomach, liver, gall bladder, urinary bladder, pancreas, small intestine and many more. The kidneys are located in the posterior and dorsal region of the cavity. The peritoneal fluid lubricates the organs suspended inside the abdominal cavity. The main function of the abdominal cavity is to provide housing for those organs.

The suspended organs in the cavity are known as the viscera, and these visceral organs are covered by the greater omentum, a portion of the peritoneum. Usually, the abdominal cavity is ventral or towards the ground, but in humans, it is towards the front side since man stays in an upright posture.

The main function of abdominal muscles is to bend the spine forward when it is coencentrically contracting. Stomach is one of the organ present inside the abdomen.

Stomach is a hollow tube like muscular organ which is an important part of our digestive system. Stomach is present between esophagus and the small intestine. Stomach aids in digestion by secreting digestive enzymes and gastric acid. Stomach is present just below the diaphragm on the left side. In anatomy, stomach is divided into four sections: cardia, body, fundus and pylorus. Stomach is connected to the lower esophagus through gastroesophageal sphincter which is responsible for keeping the food contents inside the stomach.
