What is Gut Flora?
The human digestive tract begins in the mouth and extends to the rectum. The intestinal flora refers to microorganisms based in the digestive tract. These microorganisms are generally harmless. Their distribution varies along the location of the intestine and between individuals. They play an important role in the protective, structural and metabolic functioning of the intestine.
bacteria are dominant microorganisms in the intestine. It is dominated by both the Jejunum and the ileum of the distal small intestine and the large intestine. Sour, pancreatic and bile secretions prevent their colonization of the stomach and duodenum proximal small intestine. Aerobic bacteria, such as aerobic lactobacilli and enterococci, are the dominant intestinal flora in Jeun and Ileum, and the large intestine is dominated by anaerobic bacteria, such as bifidobacteria, Escherichia coli and anaerobic lactobacilli. There may be some changes in the bacterial population in the adult intestine when age, diet, lifestyle and environment are changed.
under normal conditions has a human host and its stRound flora Symbiotic relationship in which they are both beneficial. The human host provides food and a stable environment for the intestinal flora. Meanwhile, the intestinal flora provides the benefits to its human host by preventing colonization of harmful bacteria in the intestine, preventing intestinal inflammation, contributing to the development of the immune system, strengthening food and water absorption, and synthesizing vitamins K and B 12
The growth of harmful bacteria is prevented by a barrier effect, which means that adherence to intestinal flora on the intestinal lining competes and inhibits the invasion of harmful bacteria. Its role in preventing intestinal inflammation and contributing to the development of the immune system is attributed to the ability of the intestinal flora stimulates lymphoid tissue in the intestine to form antibodies to harmful bacteria. Lymphoid tissue growth can also be caused by short chain fatty acids, which are PRoducts of fermentation of carbohydrates with bacteria. In addition, short chain fatty acids control proliferation and differentiation of cells lining the intestine, which help prevent damage to the intestinal lining.
In addition to fermentation of carbohydrates, enzymes produced by intestinal flora also increase carbohydrate absorption. These enzymes spend carbohydrates into a form of useful energy and nutrients for humans. In addition, the absorption of water and diet minerals such as iron, calcium and magnesium, which are also necessary in the metabolic functions of the human body, is also increased.
