Question

Why is the stomach such a muscular organ? How is the stomach lining adapted to its function?

Answer 1

The stomach is referred to as a hollow muscular organ in the digestive system. It is one of the essential organs of the digestive system altogether. It can make itself large to hold up to one liter of food. The main and major role of the stomach is to provide an acidic medium to digest the food material. It plays a role as the main site of protein digestion.

Complete answer:
The stomach is present and located between the oesophagus of the gut and the duodenum of the small intestine. It occurs in the upper left part of the abdomen, just below the lobes of the liver. The upper portion of the stomach is present close to the diagram. This can lead to the control of breathing concerning the stretching of muscles of the stomach.
The food mixes very perfectly with the acidic gastric juice of the stomach by the help of churning movement by this a thick, highly acidic, semi-liquid material prepared by the digestive juices of your stomach, which get connected with the food that we eat. It is a result of two forms of digestion - mechanical and chemical digestion and without it we do not get the required nutrients.

So, the stomach is regarded as a muscular organ.
The stomach lines are, subserosa, and serosa. These layers control churning of food i.e. it physically breaks down the food and they produce gastric juices. The digestive juices or gastric juices is made up of hydrochloric acid and pepsin which is a digestive enzyme. The stomach possesses a number of gastric glands and the major role of these glands can change depending on their location. These glands synthesise gastric juices as well as mucous. Gastric juices play a role in digestion while mucus protects the stomach lining. In this way the stomach line is adapted to function well.

Note: Although most absorption takes place in the intestine, the stomach absorbs in spite of a lot of metabolites. Amino acids, Medication, Ethanol (from alcoholic beverages) are readily absorbed in the stomach. Water is also absorbed in the stomach when dehydrated conditions occur. A peristaltic movement of the muscles enables the churning of the food in the stomach.
