A healthy body is inseparable from the health of one's digestive function. Only when one's digestive function is healthy can one maintain the health of one's body. Therefore, there are many people who pay special attention to their physical health and want to understand the basic content of physical digestion. In order for you to have a specific understanding of this aspect and to keep your body healthy, come and take a look at the introduction below.

Basic content

Food is chewed in the mouth, ground by the teeth, stirred and swallowed by the tongue, and the gastrointestinal muscles move, turning large pieces of food into small pieces. This allows the digestive juice to fully mix with the food and push the food bolus or chyme down from the mouth to the anus. This digestion process is called mechanical digestion, or physical digestion.

Chemical digestion refers to the chemical decomposition of food by digestive juices secreted by the digestive glands. The digestive juices secreted by the digestive glands break down complex nutrients into simple compounds that can be absorbed by the intestinal wall, such as carbohydrates into monosaccharides, proteins into amino acids, and lipids into glycerol and fatty acids. These decomposed nutrients are then absorbed into the body by the small intestine (mainly the jejunum) and enter the blood and lymph. This digestion process is called chemical digestion.

Mechanical digestion and chemical digestion occur simultaneously to complete the digestion process.

For example, the digestion process of bile belongs to physical digestion. rather than an enzymatic reaction.

The above content specifically introduces the basic content of physical digestion. Therefore, for many people who pay attention to their health, they can fully understand and recognize the above content.
