2-Digestion is the mechanical and chemical breakdown of food into small particles and molecules that your body can absorb and use.
3-Carbohydrates are molecules made of carbon, hydrogen, and oxygen atoms and are usually the bodies major source of energy. They are commonly found in 3 forms, starches, sugars, or fibers. All of them are made of sugar molecules that are linked together like a chain. Foods that are high in Carbohydrates are easy to digest. Good sources of carbohydrates are red beans, fruits, and vegetables
4-You need a certain amount of fat in your diet and on your body to stay healthy. Fats, also called lipids, provide energy and help your body absorb vitamins. They are a major part of cell membranes.

Most of the fats in your diet should come from unsaturated fats. Examples of unsaturated fats are fish, nuts, vegetable oils, and avocados

there are many types of enzymes. Each one is specialized to help break down a specific molecule at a specific location in the body.
9-the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wave-like movements that push the contents of the canal forward.
