smooth muscle
Mechanical digestion is aided by the action of stomach muscles. These muscles contract and relax to churn and mix food with gastric juices, breaking it down into smaller particles and facilitating chemical digestion. This process helps in the effective mixing of food with enzymes and acids, enhancing nutrient absorption later in the digestive tract.

Mechanical Digestion
The type of digestion where food is digested is called mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food into smaller pieces, while chemical digestion involves the breakdown of large molecules into simpler substances with the help of enzymes.

chemical digestion
Grinding and smashing of food is called mechanical digestion as there is no change in the food but the size of the pieces.
Lipids.
The type of energy found in food is chemical energy, which is stored in the bonds of molecules. When we consume food, our bodies break down these molecules through digestion, converting the chemical energy into usable forms, primarily ATP (adenosine triphosphate). This energy is then utilized by muscles to facilitate movement and perform various physical activities.
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.
