What is the role of absorption in the digestive system?
Two primary roles of the digestive process are absorption and secretion. The role of absorption in the digestive system is essential for the body, because without it, vitamins, minerals, carbohydrates and other nutrients that we consume could not be used without it. Absorption is a process by which nutrients in food transmit to blood. Most absorption occurs in the small intestine, the primary organ of the digestive tract.
After the food passes through the stomach into the small intestines, it is transformed into energy for the body. The absorption is made possible by Villi, small bristles in the mucosa. The mucous membrane is a wet tissue, which is closed to certain parts of the passages and organs of the body. Killi acts as channels by which nutrients derived from fission food can pass into the bloodstream and be transmitted to the rest of the body. The real absorption process is slightly different for each type of nutrient.
The vast majority of absorption in the digestive system occurs in the duodenum and jejeunum, specific parts of the small intestines located about two thirds of the way down from the entrance. Carbohydrates, tUky and proteins are cleaved and absorbed and the body sees that each of them is most used. The digestive enzymes found in the small intestine are responsible for the decay and conversion of certain foods into usable energy. Some individuals lack specific enzymes, resulting in an inability to spend certain nutrients. The inability to spend or change certain foods into usable energy means that these nutrients are not absorbed but remain in the digestive system.
While most of the absorption occurs in the small intestines, absorption is also important for the large intestine. Undigested and unused nutrients from foods that are not absorbed in the small intestine. The organization absorbs water and sodium and the process of exchanges will change undigested and unnecessary nutrients into waste, which is excreted as fecal matter.
Fecas are mostly water, the volume consisting of bacteria and undigested matter. Mucus is what acts as a bile binder, which gives "normal" sprays a solid composition. Interference withA surplus of mucus, bacteria, undigested and non -absorbed foods is what changes the composition of the bowel movements from normal to abnormal, it serves as an indicator that there are virus, bacteria transmitted by food or digestive problems. If the body somehow disrupts the absorption into the digestive system, other symptoms may occur, including stomach spasms, nausea, digestion and vitamin deficiency.
