Where does the digestion of food end?
Digestion of food ends in the small intestine.
- Function of the small intestine:
The small intestine is where most of the digestion and absorption of nutrients take place. It is around 20 feet long and divided into three parts - the duodenum, jejunum, and ileum.
- Digestion in the small intestine:
When food leaves the stomach, it enters the small intestine where enzymes from the pancreas and bile from the liver continue the breakdown of proteins, carbohydrates, and fats into smaller molecules such as amino acids, glucose, and fatty acids.
- Absorption of nutrients:
The walls of the small intestine are lined with tiny finger-like projections called villi which increase the surface area for nutrient absorption. Nutrients are then absorbed into the bloodstream through the villi and transported to cells throughout the body for energy, growth, and repair.
- What happens in the large intestine?
After the small intestine has absorbed all the nutrients, the remaining material enters the large intestine. The main functions of the large intestine are to absorb water and electrolytes from the indigestible food matter, forming feces, and to eliminate waste from the body through the rectum and anus.
In conclusion, while some digestion does occur in the stomach and mouth, the majority of nutrient breakdown and absorption happens in the small intestine, making it the final site of digestion in the human body.
