The Stomach
The stomach is the organ which digests the food in humans and most animals. some animals, though, have two divisions in digesting foods like birds and ruminants. A ruminant is an even toed animal which regurgitates and masticates its food after swallowing. Their stomach has three chambers, and some of the animals are cattle, goat, deer, antelope, and giraffe, which have four stomach chambers. The outer surface of the stomach is smooth, and the inside is a crumbled up layer covered with mucus. these folds help in the mixing up of food with digestive juices. They then move the material/food into the intestines. A known fact of the stomach is that only water, alcohol, and other kinds of specific drugs can be absorbed from the stomach. Most of the food absorption is taking place in the small intestine. The stomach is located on the left side of the body under the diaphragm. The diaphragm is the partition of muscles and tendons between the chest cavity and the abdominal cavity. The esophagus located to the top right of the stomach, serves as an elevator for food. An estimated time for the food to get from the mouth, through the esophagus, to the stomach is seven sec
Meat extracts, cooked grains, and partially digested products of proteins generate the flow of gastric juice. These ingredients are called secretagogues. They form the hormone gastrin in the pyloric end of the stomach. "When gastrin is absorbed it stimulates the secretory glands." Gastric secretion may also be stimulated by the sight or the smell of food, this reaction is called cephalic or reflex stimulation. When the stomach is empty the walls of the stomach are together. When food enters the stomach, the walls open and the cavity gets bigger. The part of the stomach connected to the esophagus, or the cardiac portion of the stomach, stores the ingested food. First come "waves" of relaxation for the stomachs muscular wall, then the circular muscle contracts. This is called peristalsis. This starts in the middle of the stomach and make the food travel downward and it stops just before arriving at the pyloric canal. The "waves" of relaxationa dn contraction may occur at a rate of "three per minute" they then soften the food and thoroughly mix it with gastric juice.
