Detailed explanation-1: -The food contains three macronutrients that require digestion before they can be absorbed: fats, carbohydrates, and proteins. Through the process of digestion, these macronutrients are broken down into molecules that can traverse the intestinal epithelium and enter the bloodstream for use in the body.
Detailed explanation-2: -Digestion is the process by which the food we eat is broken down into small parts. From these smaller parts, nutrients like carbohydrates, fats, proteins, vitmains and minerals are absorbed and taken to all parts of the body by the blood. Q.
Detailed explanation-3: -The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
