Functions of Stomach in Man

The stomach is a vital organ in the digestive system of humans, responsible for several important functions that aid in the digestion and absorption of nutrients.

1. Storage of Food
- The stomach acts as a temporary storage reservoir for food that has been ingested.
- When food enters the stomach, it is mixed with gastric juices and enzymes that start the process of digestion.
- The stomach can expand to accommodate a large volume of food and gradually release it to the small intestine for further digestion and absorption.

2. Digestion of Proteins
- One of the key functions of the stomach is the digestion of proteins.
- Gastric juices in the stomach contain hydrochloric acid and enzymes like pepsin, which break down proteins into smaller peptides and amino acids.
- This process is essential for the body to absorb these nutrients and utilize them for various bodily functions.
- The acidic environment of the stomach also helps to kill harmful bacteria that may be present in food, protecting the body from infections.

In conclusion, the stomach plays a crucial role in the digestive process by storing food, initiating the breakdown of proteins, and creating an optimal environment for nutrient absorption. Its efficient functioning is essential for maintaining overall health and well-being.
