Definition
Stomach is a J shaped Organ, which expands as food enters it.
Functions of Stomach
Storage of Food
Because the food is processed batch by batch and it takes time.
Mixing of Food with Digestive Juices
The muscular walls of the stomach help in mixing the food with digestive juices.
Mechanical Churning
Regulation and flow of food into small intestine
By the pyloric sphincter.
Partial digestion
This is done by the gastric glands present in the wall of the stomach. These produce Hydrochloric Acid which is used to create an acidic medium to activate the enzyme Pepsin. Mucus is produced to protect the inner lining of the stomach from the acid.
The food in the stomach is then moved to the Small Intestine by the pyloric sphincter
