digestin

Digestin refers to the process by which an organism breaks down food into smaller molecules that can be absorbed into the bloodstream and used for energy, growth, and repair. This complex process involves both mechanical and chemical actions. Mechanical digestion begins in the mouth with chewing, which breaks food into smaller pieces, and continues in the stomach with churning. Chemical digestion involves the action of enzymes, which are specialized proteins that speed up chemical reactions. These enzymes, secreted by various glands and organs in the digestive system, break down carbohydrates, proteins, and fats into their simpler components.

The digestive system is a series of organs that work together to process food. It includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. Accessory organs like the salivary glands, liver, gallbladder, and pancreas also play crucial roles by producing enzymes and other substances necessary for digestion. Food travels through the digestive tract, undergoing mechanical and chemical breakdown at each stage. Absorption of nutrients primarily occurs in the small intestine, where digested molecules pass through the intestinal walls into the bloodstream. Undigested material then moves to the large intestine, where water is absorbed, and waste products are formed and eventually eliminated from the body.
