GENERAL HISTOLOGY

Detailed explanation-1: -The majority of chemical digestion occurs in the small intestine. Digested chyme from the stomach passes through the pylorus and into the duodenum. Here, chyme will mix with secretions from both the pancreas and the duodenum. Mechanical digestion will still occur to a minor extent as well.

Detailed explanation-2: -Chemical digestion takes place throughout your digestive tract. Chemical digestion begins in your mouth with your saliva. The process continues in your stomach and is completed in your small intestine. The majority of chemical digestion takes place in your small intestine.

Detailed explanation-3: -As food travels from your mouth into your digestive system, it’s broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion.

Detailed explanation-4: -Chemical digestion, through a process called hydrolysis, uses water and digestive enzymes to break down the complex molecules. Digestive enzymes speed up the hydrolysis process, which is otherwise very slow.

Detailed explanation-5: -Carbohydrates must be broken down into simple sugars, proteins into amino acids, lipids into fatty acids and glycerol, and nucleic acids into nitrogen bases and sugars. Some chemical digestion takes place in the mouth and stomach, but most of it occurs in the first part of the small intestine (duodenum).
