Hint The gastrointestinal system is important to the physical body. It helps break down the foods we fret into smaller components which will be absorbed by the cells in our body for energy. The method of digestion involves grinding of the food, moving food through the alimentary canal, breaking down large molecules, absorption of nutrients into the blood, and removing waste from the body.

Complete answer
The main function of the tiny intestine is the absorption of nutrients and minerals. The tiny intestine is split into three regions, namely duodenum, jejunum, and ileum. Within the duodenum, the absorption of food begins. The bile and digestive juice enter during this part. The jejunum is the second part of the tiny intestine. It consists of various finger-like projections called villi and microvilli which helps within the absorption of food into the bloodstream. Also, villi also increase the area. Hence, the utmost absorption of food occurs here. Within the last part of the intestine, the ileum absorbs vitamin B12, bile acids, and remaining nutrients.

Additional information
The gastrointestinal system is formed from the alimentary canal and therefore the digestive organs—a group of organs that everyone has their own job within the digestive process. The alimentary canal is one long tube that starts at your mouth and ends at the anus. During an adult, the alimentary canal is about 23 feet long.

So the correct answer is ‘Both assertion and reason are correct and therefore the reason is that the correct explanations for assertion’.

Note: This one long container of the stomach related framework—the stomach related parcel—incorporates the throat, stomach, digestive tract, and tremendous digestive tract close by adornment organs simply like the liver, gallbladder, pancreas, and salivary organs. The alimentary canal of a traditional adult person is about 30 feet long.
