In the human body (and in that of other animals) there is a Digestive System so that with the help of it the food we eat can be transformed into simpler substances and that in this way the body can absorb them, at this This process is known as digestion, during this transformation the food is broken down into smaller molecules through a mechanical and chemical-enzymatic process, in other words there is a development of carbohydrates, lipids and proteins into substantial elements that are more practical and easier to absorb and transport through the blood.
In the digestive system is where digestion occurs, another name by which it is known is as the digestive system, it is composed of a large number of organs belonging to the human body, which are: mouth and oral cavity, pharynx, esophagus, stomach, large intestine, small intestine and anus. However, it must be taken into account that digestion is not a single single process, but is formed by several transformations that fulfill their purpose, that is, in the digestive system it occurs: the chewing of food, the transfer of food, secretion of digestive juices, all those substances necessary for the development of the body are absorbed because they are nutrients, and finally defecation occurs, because there are components of food that are not useful for the body and for this reason discards them.
Nowadays, thanks to the evolution of man, a great variety of artificial foods have been created and with more chemicals than those that existed previously, therefore the digestive system of the human being is one of the most complex, because we consume foods that are not included in the diet of other animals. Among the most common diseases that can occur in the digestive system are the following: allergy to food or cow's milk protein (lactose), anemia, constipation, diarrhea, stomach cancer, colitis, irritable bowel syndrome, peptic ulcer, stomach cancer and a few others.
