Process of Digestion

Digestion begins in the mouth, where mechanical and chemical processes commence. Chewing breaks food into smaller particles, while saliva, rich in enzymes, begins the breakdown of carbohydrates. Once swallowed, the food travels down the esophagus via peristalsis—muscular contractions that push it toward the stomach.

In the stomach, powerful acids and enzymes further decompose food. Here, proteins are primarily targeted, allowing nutrients to be prepared for absorption later. The partially digested food, now called chyme, gradually enters the small intestine.

The small intestine is where the bulk of digestion and nutrient absorption occurs. It has three segments: the duodenum, jejunum, and ileum. Enzymes from the pancreas and bile from the liver contribute to digesting fats, carbohydrates, and proteins. The small intestine's inner surface is lined with villi, tiny finger-like projections that increase surface area and facilitate absorption.

After passing through the small intestine, the remaining waste material enters the large intestine, where water is absorbed, and the final waste is prepared for elimination.

Nutrient Absorption

Nutrient absorption primarily occurs in the small intestine, an essential aspect of the digestive process. The nutrients extracted from food are classified into macronutrients and micronutrients. Macronutrients like carbohydrates, proteins, and fats provide energy and are absorbed primarily in the jejunum. Micronutrients, including vitamins and minerals, are also absorbed here, though some may require specific conditions or transport methods.

The effectiveness of absorption relies on several factors:

The surface area of the intestine
Functionality of digestive enzymes
Presence of other substances in the gut
