The maximum absorption of digested food occurs in the small intestine of the alimentary canal. The small intestine is the longest part of the alimentary canal, measuring about 6 meters in length. It consists of three parts - the duodenum, jejunum, and ileum.

1. Structure of Small Intestine:
The small intestine has a large surface area due to the presence of numerous finger-like projections called villi, which are covered with microvilli. These structures increase the surface area of the small intestine, allowing for more efficient absorption of nutrients.

2. Digestion in Small Intestine:
The small intestine plays a crucial role in the digestion of food. The duodenum receives digestive enzymes from the pancreas and bile from the liver, which help to break down food molecules into smaller units. The jejunum and ileum further break down these molecules into simpler forms like amino acids, glucose, and fatty acids.

3. Absorption in Small Intestine:
The small intestine is responsible for the absorption of most of the nutrients from the digested food. The villi and microvilli present in the small intestine increase the surface area for absorption. The nutrients are absorbed into the bloodstream and transported to the liver, where they are processed and distributed to other parts of the body.

4. Importance of Small Intestine:
The small intestine is a vital organ in the digestive system, and its proper functioning is essential for the overall health of an individual. Any disruption in its functioning can lead to malabsorption of nutrients, resulting in various health problems.

In conclusion, the small intestine is the site of maximum absorption of nutrients from the digested food. Its structure, digestion, and absorption processes make it an essential organ in the digestive system.

Maximum absorption of digested food occurs in the small intestine.

Explanation:
The alimentary canal is a long tube-like structure that begins at the mouth and ends at the anus. It is responsible for the digestion and absorption of food.

The small intestine is the longest part of the alimentary canal, measuring about 6 meters in length. It is divided into three parts: the duodenum, the jejunum, and the ileum.

The small intestine is responsible for the absorption of most of the nutrients from the digested food. The inner lining of the small intestine is covered with finger-like projections called villi, which increase its surface area for absorption. The villi are also covered with microvilli, which further increase the surface area.

The small intestine receives digestive juices from the pancreas and the liver, which help in the breakdown of food. The enzymes in the small intestine break down carbohydrates, proteins, and fats into simpler molecules that can be absorbed by the villi.

The nutrients are then transported across the intestinal wall and into the bloodstream, which carries them to the liver for processing and distribution to the rest of the body.

In conclusion, the small intestine is the site of maximum absorption of digested food due to its large surface area and the presence of digestive enzymes and transporters.
