The bolus is liquefied in the ________ and it is now called chyme.
Strike441 [17]

Answer:

The options:

A) esophagus

B) stomach

C) small intestine

D) mouth

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.

dusya [7]

The correct answer is neuroplasticity.

Neuroplasticity or brain plasticity is the property of the brain to change. Neuroplasticity can be observed at different levels. For example, changes at the cell level can affect connections between neurons (synaptic plasticity), while non-synaptic plasticity refers to changes in the intrinsic part of the neuron. On the other hand, larger-scale changes are usually made by environmental stimuli. Emotions may cause neuroplastic change through activity-dependent plasticity, which is significant for the recovery from brain damage.
