The question says, so here in this question, the path of the food is given and we have to pick out which one of the following is not in the order of the organ which the food passes.
00:16
So food we all know is a source of energy and food majorly is made up of the building blocks like carbohydrate, fat and lipids and fibers etc.
00:29
So these are nothing but the primary metabolites which are directly involved in the growth and metabolism of a organism.
00:38
And these are very essential for an organism in daily basis for his or her survival.
00:46
So to extract the energy from the food material, the food under goes a process which is a cascade of series of many phenomena that is called as digestion.
00:58
And this digestion process, it begins as soon as they put a food inside that is in the mouth itself.
01:08
So mouth, how does it help in the digestion process? let us see.
01:13
Mouth has teeth and also salivary organ.
01:17
So teeth helps in digestion by the process called as mastication, that is chaving of the food, that is the mechanical return of food.
01:25
Saliva moistens the food hence what happens it aids in better digestion in mouth also the carbohydrate breakdown takes place so how we can ask is that the saliva contains many enzymes and also specifically it contains the salivary amylase which helps to break down the carbohydrates so after the mouth the food travels to the pharynx where the process of swallowing the food to the esophageal region takes place.
02:02
Okay, now the food is called as the bolus.
02:05
From the pharyngeal region, the food travels to the esophagus or the food pipe.
02:12
So here it acts as a passage in between the mouth and also to the stomach.
02:18
So it is a pipe like structure...
