The Answer is B) Small Intestine

Explanation:

The alimentary canal is a long muscular tube that begins at the mouth and ends at the anus. It is responsible for the digestion and absorption of food. The liver is an important organ that produces bile, which helps in the digestion and absorption of fats. The bile produced by the liver is stored in the gallbladder and released into the small intestine.

Parts of Alimentary Canal:

The alimentary canal is composed of several parts, which are as follows:

1. Mouth
2. Pharynx
3. Oesophagus
4. Stomach
5. Small intestine
6. Large intestine
7. Rectum
8. Anus

Function of Small Intestine:

The small intestine is the longest part of the alimentary canal and is responsible for the majority of nutrient absorption. It is divided into three sections: the duodenum, jejunum, and ileum. The duodenum is the first section of the small intestine and is responsible for receiving the partially digested food from the stomach. It is also the part of the small intestine that receives bile from the liver.

Role of Liver and Bile:

The liver produces bile, which is stored in the gallbladder. Bile helps in the digestion and absorption of fats by breaking down large fat molecules into smaller ones. When the partially digested food enters the duodenum, the gallbladder releases bile into the small intestine. The bile mixes with the partially digested food, and the fats are broken down into smaller molecules that can be absorbed by the body.

Conclusion:

In conclusion, the small intestine receives bile from the liver. The bile helps in the digestion and absorption of fats by breaking them down into smaller molecules. The small intestine is responsible for the majority of nutrient absorption and is an important part of the alimentary canal.

Bile is secreted by the liver and is stored in the gall bladder from where it enters the small intestine via a common duct.
Hence, option B is correct..
