GENERAL HISTOLOGY

Detailed explanation-1: -Digestion is a process that converts nutrients in ingested food into forms that can be absorbed by the gastrointestinal tract. Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine.

Detailed explanation-2: -Chemical digestion is a vital part of the digestive process. Without it, your body wouldn’t be able to absorb nutrients from the foods you eat. While mechanical digestion involves physical movements, such as chewing and muscle contractions, chemical digestion uses enzymes to break down food.

Detailed explanation-3: -The stomach makes several digestive juices and enzymes that mix with food. Next, the stomach’s strong muscles act like a blender to turn food into a useable form. This process takes longer for some types of foods than others. Carbohydrates, for example, break down the fastest.
