</h2><h2>i) Mechanical and ii) chemical digestion. </h2>
Explanation:
There are two kinds of digestion;
i) Mechanical and ii) chemical digestion.
Mechanical digestion involves physically breaking down the food into smaller pieces. It begins in the mouth as the food is chewed.
In the Stomach
The stomach is a muscular sac with three important functions:
i) It mixes and stores food until it can be further digested.
ii) It secretes chemicals that help break the food into more digestible forms.
iii) It controls the passage of food into the small intestine.
Chemical digestion involves breaking down the food particles into simpler nutrients that can be used by the cells.
In stomach, chemical digestion of mostly proteins occurs Secretions from the stomach lining consist of about two liters of HCl, pepsin, and other many fluids that make up gastric fluids. The fluid is acidic and it helps kill bacteria and many other pathogens. It also produced by the stomach lining usually keeps the acids from damaging the lining. If no mucus or too much acid is produced, peptic ulcers form.
