Let's Learn About Human Digestive System

Digestion - a process that we all carry unconsciously, is engaged in the organism on the reflex level. The process is complex, so the question is legitimate onlooker "What is Digestion?". From the doctor's perspective, it is the processing of food, physical and chemical. As a result, it becomes possible absorption of substances, as well as waste management which is if not well cleanse, it will cause a blockage in colon. So make sure to do a cleanse every week to avoid or relief bowel blockage at home.

Digestive organs - communicating hollow organs, supplemented glands that help break down the chemical bonds in materials. For example, carbohydrates are potatoes and bread are carbohydrates in the form of starch, they can not be acquired until the starch molecules are broken down to glucose. Meat protein itself is also not able to be absorbed - it must be expanded to make up - amino acids (of which the body can build its own protein). Fats on their own can not be within the medium of the body - only after both of them are obtained by digestion fatty acids and glycerol. If not well digested, it may cause a colon obstruction which is can lead to cancer.


Physiology of digestion is that substance which, although located within the body, not in the organism. They would have to undergo many transformations. And then through the thin mucous are absorbed. Digestive organs also include liver, salivary glands and pancreas. In addition, in the wall of the digestive gland is producing the desired substance for digestion. All of the walls are covered with mucus, thus reducing the probability injure delicate shell.

Food mechanically treated teeth, then it is mixed with saliva. Saliva is consist of three pairs of large glands and many smaller ones. This fluid contains organic ingredients, minerals and breakdown products of leukocytes. But the main thing - it contains two enzymes - ptyalin (breaks down starch) and maltase (breaks down sugar rye, barley, etc). From the mouth through the pharynx the food enters the esophagus.


Esophagus - The tube that can be called fairly straightforward. It is covered by stratified squamous epithelium. These cells are constantly updated, because they are very easy to injure. Division occurs in the deeper layers, while the outer exfoliated and down into the stomach with food. In a small number of submucosal glands - cancer of the esophagus. They look around the stomach to secrete substances to stomach, they are named after cardiac cancer. In the beginning a lot of the striated muscles of the esophagus, but in the lower third is only smooth muscle fibers. Swallowing begins consciously, but then turned on a reflex response. Esophagus after food ingestion involved such as the stomach and intestines.

Stomach works as an excellent mixer through muscle. In this body begins proteolysis by the enzyme pepsin, hydrochloric acid kills bacteria. As a result of digestion in the stomach turns semi-liquid contents evenly chopped - chyme. Sucked out of it there are some salt water and some medications. The stomach produces molecules antianemic factor. If you're having such intestinal obstruction symptoms, it's probably that the enzymes in stomach area are not functioning properly.

After food enters the small intestine. The length of it - an average of six meters. The first 30 cm - duodenum. It is attached to the adjacent organs and goes around the head of the pancreas. Then goes into the jejunum and then the ileum. In the small intestine completes the process of digestion and selectively products of digestion are absorbed into the blood and lymph. The small intestine has special education - hairs that greatly increase the suction area. At the gut flow ducts from the liver (bile) and pancreas. As a result, it is here finally digested and absorbed carbohydrates, fats and proteins. And fats come directly into the lymph, which then connects to the blood.

In the large intestine complete the digestion residues, but "for himself" putrefactive bacteria. Absorbed water, and debris get consistency of feces. In the final section, rectum wastes waiting to be removed in the process of defecation. Thus ends the process of digestion. It is important all the organs of the digestive system, but their teamwork can help the body's cells to be updated with the availability of building material for cells.
