Answer 1

Functions of digestive system

Explanation:

The correct answer for this question is (D) transport nutrients to other organs.

1. Options (A) Ingestion of food is a major function of digestive system where the food enters into alimentary canal through the mouth. There, the food is chewed and mixed with saliva containing enzyme that begin breaking down the carbohydrates in the food  and some lipids digestion takes place. Therefore, this can't be the right answer.
2. Option (B) In chemical digestion, digestive secretions break down complex food molecules into their chemical building blocks (eg:- proteins into separate amino acids). This process gets completed in small intestine. Therefore, this can't be the right answer.
3. Option (C) In absorption, the nutrients are absorbed from the lumen of the alimentary canal into the bloodstream through the epithelial cells.Therefore, this can't be the right answer.
4. Option (d) Transportation of nutrition to the other organs are done by circulatory system from the tubes which carry blood around the body and not by digestive system. It transports water and nutrients to the rest of our body. Therefore, this is the right answer.
