The CORRECT ANSWER IS B)
B) stomach
Explanation:
The digestive tract — often termed the gastrointestinal tract or alimentary canal — supplies the route via which foods passes through the body. In the course of this pathway, foods are digested into its constituents nutrients necessarily for absorption.
Digestion initially starts in the mouth, with enzymes in saliva dissolving carbohydrate (starch). In the course of chewing, the food is lubricated, a little bit of hear is used up, and less difficult to swallow and digest. The teeth and mouth aid conversion of each morsel of food to a bolus which flows right into the esophagus (“gullet”). In the course of chewing, taste buds stationed in the mouth gives pleasure to every mouthful — or to taste if not okay. Once the bolus is swallowed, it flows through the esophagus, it is kind of warmed and lubricated as it flows into the stomach.
Note:
The acidic condition of the STOMACH and the effect of gastric enzymes turns the bolus to CHYME, A LIQUEFIED MASS that is moved from the stomach to the small intestine.
