Question

What is the difference between mechanical digestion and chemical digestion?

Answer 1

Hint: To answer this question, we first need to understand what digestion is. Large insoluble food molecules are broken down into little water-soluble food molecules during digestion, allowing them to be absorbed into the watery blood plasma. These tiny molecules are taken into the bloodstream by certain organisms through the small intestine.

Complete answer:
Mechanical digestion: Mechanical digestion is a purely physical process that has no effect on the food's chemical composition. Instead, it reduces the size of the food to maximize surface area and movement. Mastication, or chewing, and tongue movements help break down food into tiny pieces and mix it with saliva.
Chemical digestion: Enzymes are secreted throughout the digestive tract during chemical digestion. The chemical connections that hold food particles together are broken by these enzymes. Food can then be broken down into little, digestible pieces.
Difference between mechanical digestion and chemical digestion:
Mechanical and chemical digestion are two processes in the digestive tract that allow food to be digested, absorbed, and excreted. The major distinction between mechanical and chemical digestion is that mechanical digestion involves the mechanical breakdown of large food particles into little food particles, whereas chemical digestion involves the chemical degradation of high molecular weight compounds into low molecular weight ones. Chemical digestion takes place from the mouth to the intestine, while mechanical digestion takes place from the mouth to the stomach. The stomach plays an important role in both mechanical and chemical digestion.

Note:
Food must be broken down into nutrients for the body to use for energy, development, and cell repair. Before the circulation absorbs and transports nutrients to cells throughout the body, food and drink must be broken down into smaller nutrition molecules.
