Answer:
The main function of stomach is to serve as a temporary storage chamber and primarily breaks down food by mechanical means.
Explanation:
The stomach is a muscular organ located on the left side of the upper abdomen.It secretes acid and enzymes that digest food.The stomach muscles contract periodically, churning food to enhance digestion (breaking down of food by mechanical means). The stomach is made up of several layers of tissues
The mucosa (mucous membrane) is the inner lining of the stomach.
Next is the sub mucosa.
The muscularis propria (or muscularis externa) is the next layer that covers the submucosa. It is the main muscle of the stomach and is made up of 3 layers of muscle.
The serosa is the fibrous membrane that covers the outside of the stomach.
The stomach has 3 main functions:
1.temporary storage for food, which passes from the esophagus to the stomach where it is held for 2 hours or longer
2.mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach
3.digestion of food
The stomach secretes various secretions containing enzymes which breaks down food chemically and the muscles mechanically break down the food.Food is broken down into a thick, acidic, soupy mixture called chyme, which enters the intestine.
