Small Intestine
The complete digestion of food occurs in the small intestine.
Function of Small Intestine
- The small intestine is where the majority of chemical digestion and nutrient absorption takes place.
- Enzymes from the pancreas and bile from the liver help break down food particles into smaller molecules that can be absorbed by the body.
Process of Digestion in Small Intestine
- After food passes through the stomach, it enters the small intestine where further breakdown of proteins, carbohydrates, and fats occurs.
- Enzymes in the small intestine help break down these macromolecules into smaller units like amino acids, simple sugars, and fatty acids.
- Villi and microvilli in the small intestine increase the surface area available for absorption of these nutrients into the bloodstream.
Importance of Small Intestine
- The small intestine is crucial for the absorption of nutrients such as vitamins, minerals, and other essential substances that are needed for the body to function properly.
- The nutrients absorbed in the small intestine are then transported throughout the body to provide energy and support various physiological processes.
In conclusion, the small intestine plays a vital role in the complete digestion of food and the absorption of essential nutrients that are necessary for maintaining overall health and well-being.

Where does the complete digestion of food occur?a)Stomachb)Large intes...
The correct answer is *c) Small intestine*.
Here's why:
- *Mouth (d)*: Food is broken down mechanically by chewing and mixed with saliva that contains enzymes to break down carbohydrates. However, digestion is not complete here.
- *Stomach (a)*: The stomach further breaks down food with its acidic environment and digestive enzymes like pepsin, which primarily targets proteins. Still, digestion is not complete.
- *Small intestine (c)*: This is where most of our nutrient absorption occurs. The small intestine receives bile from the liver and pancreatic juice from the pancreas, which contain enzymes to break down proteins, carbohydrates, and fats into their simplest forms (amino acids, sugars, and fatty acids/glycerol). These nutrients are then absorbed into the bloodstream.
- *Large intestine (b)*: The large intestine's primary role is water absorption and storing waste until it's eliminated. Some fermentation of undigested carbohydrates occurs here, but it's not the site for complete digestion.
Therefore, the small intestine is where the complete digestion of food occurs, making nutrients available for absorption.
