Absorption of digested foodstuffs occurs in the small intestine.
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
Mechanical digestion is produced by breaking down and chewing food. This process involves the physical breakdown of food into smaller pieces that can be further digested and absorbed by the body.
During a chemical change, new substances are always formed as bonds between atoms are broken and reformed. This results in a rearrangement of atoms, causing a change in the chemical properties of the original substances. Energy is often released or absorbed during these reactions.
Mechanical digestion is the physical mashing and pulling apart of food like chewing your food. Chemical digestion uses acids and enzymes to chemically break down the food until it is small enough to be absorbed through the wall of the small intestine.
The two main phases of the digestive process are the mechanical digestion phase, which involves physically breaking down food through chewing and the movement of the stomach and intestines; and the chemical digestion phase, where enzymes and stomach acids break down food into smaller molecules that can be absorbed by the body.
