What is digestion
Digestion is the process by which the body breaks down food into small molecules that can be absorbed and used for energy, growth, and repair. It begins in the mouth, where food is chewed and mixed with saliva, and continues in the stomach and small intestine, where enzymes and stomach acids break down food further. Nutrients are then absorbed into the bloodstream through the walls of the small intestine, and waste products are eliminated from the body through the rectum and anus.
Digestion is the process by which your body breaks down food into smaller particles that can be absorbed into the bloodstream and used for energy, growth, and repair. It begins in the mouth where food is chewed and mixed with saliva. The saliva contains enzymes that start breaking down carbohydrates. Next, the food moves down the esophagus and into the stomach.
In the stomach, the food is mixed with stomach acids and enzymes to break down proteins. It then passes to the small intestine, where it is further broken down by enzymes from the pancreas and bile from the liver. The small intestine absorbs the nutrients, such as sugars, amino acids, and fatty acids, into the bloodstream.
The remaining undigested waste then moves into the large intestine, also known as the colon. Water is absorbed in the colon, and bacteria break down any remaining food particles. Finally, the waste is eliminated from the body through the rectum and anus.
Overall, digestion involves mechanical and chemical processes to break down food, absorb nutrients, and eliminate waste.
