Our first stop is going to be the mouth! You will notice that ingestion of foods occur through the mouth, as well as mechanical digestion.
In the mouth you will find teeth which break down the food you put into your mouth. This is the mechanical digestion in the digestion process.
You can also find saliva which contains Amylase enzymes. These enzymes break down starches and turn them into monosaccharides and disaccarides so be careful!
Our next stop is the pharynx. Many also call this stop the throat. The pharynx is the pathway in which food goes through from the mouth to the esopgagus. In the pharynx you will also find the epiglottis which is a flap that prevents food from entering the windpipe and the lungs.
From the pharynx we will go straight to the esophagus, in here peristalsis takes place. This is when the muscles in the esophagus constrict and relax, proplusion occurs pushing us straight to our next stop..
Now to our most famous stop of the tour, the stomach! Theres alot to see in the stomach. This muscular organ secretes acid and enzymes that digest food. The absorption of food also occurs in this organ. This is also where the chemical digestion of the digestion process occurs.
The acid chemical HCL kills all harmful pathogens that shouldnt be in the body. Hydrocloric acid is in dilute form in the gastric juices in the stomach.
Pepsinogen becomes pepsin with the help of HCL. This pepsin is the chief digestive enzyme in the stomach. It breaks down proteins into polypeptides.
Our fifth stop is the accessory organs. These organs include the liver, gallbladder and pancreas. Bile plays a role in these organs.
The liver is a big organ that lies on the right side of the belly.
