How the food changes consistency and form
Through the processes carried out by our digestive system, our food undergoes consistency and form modifications. They can be mechanically and chemically broken down by digestion into smaller fragments. In order for the body to utilize food and liquids as fuel and cell building blocks, digestion reduces them to their smallest constituents.
During mechanical digestion, food is mechanically broken down into minute pieces by being ground, smashed, squeezed, and churned as it passes through the digestive tract. There is no change in the food's form; it just disintegrates into smaller pieces of the same thing. When food is digested chemically, specific digestive enzymes or tiny proteins accomplish the actual food digestion. The enzymes transform the shape of the meal into one that the body can use. The connections within the food particles are broken by chemical digestion, releasing the smaller organic molecules that make up food. Smaller organic molecules can be absorbed by body cells and used for internal processes like energy production.

How the body was able to absorb the nutrients from the foods we eat.
The majority of the nutrients in your meal are absorbed in your small intestine before being transported by your circulatory system to other areas of your body for storage or utilization. A special type of cell helps nutrients pass through the gut lining and into the circulation. Simple sugars, amino acids, glycerol, certain vitamins, and salts are transported to the liver by your blood. When necessary, your liver processes, stores, and distributes nutrients to the rest of your body.
