Detailed explanation-1: -During digestion, muscles push food from the upper part of your stomach to the lower part. This is where the real action begins. This is where digestive juices and enzymes break down the food that you chewed and swallowed. It prepares it to provide your body with energy.

Detailed explanation-2: -Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.

Detailed explanation-3: -A Brief Overview Of Chemical Energy In food, it’s a form of potential energy because it’s stored away. Then, through a process called chemical digestion, the bonds containing the stored energy are broken, releasing energy that our bodies then use. Chemical energy can also be converted from one form to another.

Detailed explanation-4: -Catabolic and Anabolic Reactions In a catabolic reaction, molecules are broken down into smaller components, and energy is released. The breakdown of food in digestion is a catabolic reaction (see digestive system).
