The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food.

What is the job of the stomach?
The stomach is a hollow organ, or "container," that holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a usable form. Cells in the lining of your stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process.
What is inside your stomach?
The abdomen contains all the digestive organs, including the stomach, small and large intestines, pancreas, liver, and gallbladder. These organs are held together loosely by connecting tissues (mesentery) that allow them to expand and to slide against each other. The abdomen also contains the kidneys and spleen.
What are the 4 main functions of the stomach?
The four key components of gastric digestive function are its function as a reservoir, acid secretion, enzyme secre- tion and its role in gastrointestinal motility.
How big is the stomach?
Most adults have roughly the same size stomach, even though people can weigh different amounts. Your empty stomach is about 12 inches long by 6 inches across at its widest point. As an adult, your stomach can expand to hold about 1 quart of food.
Can you live without a stomach?
It may be surprising to learn a person can live without a stomach. But the body is able to bypass the stomach's main function of storing and breaking down food to gradually pass to the intestines. Absent a stomach, food consumed in small quantities can move directly from the esophagus to the small intestine.
How is the stomach made up?
The stomach wall is made up of several layers of mucous membrane, connective tissue with blood vessels and nerves, and muscle fibers. The muscle layer alone has three different sub-layers.
How is food digested in the stomach?
After you swallow, peristalsis pushes the food down your esophagus into your stomach. Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.
What are the 6 main functions of the digestive system?
The six major activities of the digestive system are ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination. First, food is ingested, chewed, and swallowed. Next, muscular contractions propel it through the alimentary canal and physically break it down into tiny particles.
Can your belly burst?
Sadly, yes. There are cases where the stomach becomes so large that it ruptures from the sheer volume of food within it. One 23-year-old lady had over 2,500ml within her stomach, which caused it to swell so much that it filled the whole of her abdomen, from her ribs to her pelvis.
What is the shape of the stomach?
The stomach is a J-shaped organ in the upper belly (abdomen). It's part of the digestive system.
Where is stomach found?
The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter.
What can you eat if your stomach is removed?
Eat a variety of foods including fruits, vegetables, whole grains, protein-rich foods and dairy, which provide a good balance for every meal. Try not to go for more than 2 or 3 hours without eating. Carry healthy snacks so you can take a bite here and there.
Can your stomach grow back after removal?
Some evidence suggests that this is possible. In fact, slight, permanent stretching may be normal. As you are able to eat more food (especially when meeting protein goals), your new stomach may stretch slightly, but this happens over a very long period of time- several years.
