What is chemical digestion?

Chemical digestion is a process by which the mammal body reduces food to size, where it can be the nutrients it contains, to absorb into the bloodstream. The process begins in the mouth, continues in the stomach and ends when the fission particles move through the small intestine for absorption. Proteins in the mouth, stomach and intestine called enzymes are primary facilitators of chemical digestion. Teeth help in this process by providing mechanical digestion. After the food has been sufficiently broken, it is swallowed and travels to the stomach over the esophagus.

When the food reaches the stomach, various hormones start the body to release enzymes that continue to spend food. Pepsin is the name of the enzyme that decomposes most of the proteins in the diet. Chemical digestion of carbohydrates, which began in the mouth of an enzyme called amylase, also continues here. This stage of digestion can take several hours depending on the animal species, but in humans it usually takes one to two hours after which the food moves to the small intestine.

After leaving the stomach, food is now a thick liquid called Chyme. Chym moves through the thin intestines, where it is exposed to several different liquids. The most important of them is called bile. The bile room changes fats into a mold that allows their chemical digestion. During this phase of the digestive process, the small intestine also absorbs more nutrients from Chyme and introduces them into the bloodstream.

In the last stage of chemical digestion occurs in the final area of ​​the small intestine, called ileum. In this area there are two enzymes called protease and carbohydrase relaxed and completed the digestion of proteins and carbohydrates. As it remains from the originally swallowed food, leaving the small intestine, entering the large intestine, where the process of chemical digestion ends.

Although mammals mostly monitor this accurate process, some other animals use chemical digestion to extraction nutrients from food. Depending on the actual type of animal could this process pUse different enzymes or occur in different internal organs. The exact nature of chemical digestion, which is not a rate, varies from species to species.
