The human stomach stores, breaks down and sanitizes ingested food prior to its entering the intestines for digestion and absorption. It allows humans to eat far more at once than they could actually process through their intestines. It is also very important for certain types of digestion, particularly the digestion of proteins that stomach acids and enzymes affect strongly.Continue Reading
The stomach is a very stretchy organ able to expand up to a gallon in capacity in some people, although the stomach works much better and is more comfortable at half that capacity. The stomach typically stores digested food for one or two hours before beginning to move it into the small intestine. During this time, it releases a substance called gastric juice, which is a mixture of mucus, hydrochloric acid and enzymes. This substance kills many of the bacteria in the food and helps break down various components in the food.
Of course, the stomach itself is made of protein substances, so if unprotected, the gastric juice would break down the stomach as well. To compensate, the stomach generates a thick coating of mucus with enzyme inhibitors and bicarbonate to break down stomach acid. Once the food is released from the stomach, it first travels to the duodenum where it is mixed thoroughly with bicarbonate to neutralize any remaining stomach acid.Learn more about Organs
The small intestine is a part of the human body's digestive system, coming after the stomach and before the large intestine in the sequence of food digestion. At 5 meters long, it is also the longest organ in the digestive system, though it is significantly narrower than the large intestine.Full Answer >
The function of the stomach is to store and partially digest food. The stomach is a J-shaped sack that lies between the esophagus and the small intestine.Full Answer >
The stomach stores swallowed and digested food, mixes it with digestive juices, and empties its contents into the small intestine. The stomach is part of the body's gastrointestinal tract, according to the National Institute of Diabetes and Digestive and Kidney Diseases.Full Answer >
Food digestion and nutrient absorption take place primarily in the small intestine, according to eMedicineHealth. Nutrient absorption is facilitated by villi and microvilli, fingerlike projections from the intestinal wall that serve to increase the surface area of the intestine so that nutrients can be fully absorbed.Full Answer >
