Smooth muscles are found in the intestines and stomach. If these were skeletal muscles, instead of smooth, you would have to physically think about digesting your food to control digestion, and no food would get digested while you were busy or sleeping!
it is the smooth muscles only.
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.

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.

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.
In the mouth, the muscle help the teeth in cutting and breaking the food particles. In the gastrointestinal tract, smooth muscles are present in the walls of the gastrointestinal tract ,and they help in the peristalsis which are the muscle contractions that produce the bowel movements which help in the movement of food (chyme) comming out of stomach into the intestines and through the intestines. Also, muscles help closing and opening the sphincters present throughout the gastrointestinal tract.
