What are Peyer's patches?
Patcher spots are areas of specialized tissues in the lower area of the small intestine that work to distinguish a friend from the enemy because the food passes through the gastrointestinal tract. Sensed cells inside these areas identify antigens and decide whether they are harmless, associated with foods that a person consumes nutrition or harmful, and associated with organisms such as bacteria that could try to colonize the body. Peyer's patches pass the word to the rest of the intestinal tract, making it easier to digest and absorb nutrients or immune attack on the attacker. Other lymphoid tissue, known as the lymphoid tissue associated with the intestine (GALT), can be found in other intestinal areas. When people are young, these areas are highly visible and easy to distinguish. With aging, they tend to disappear and become less pronounced. The minor ovoid nodes that line the intestine. As the food goes through, the antigens in the diet are presented by tissues and determines whether it recognizes and how they are classified. In addition to recognitionPeyer patches can also learn to identify new antigens and save this information for the future reference to the streamlining of the immune system.
Sometimes the immune system is confused to identify the antigens with which it interacts. It may be mistaken that antigen as a protein found in peanuts is truly harmful, and when identifying this antigen evokes an answer. The reaction leads to inflammation when a confused immune system attempts to neutralize what they think is a harmful attacker. Food allergies can lead to reactions that differ from a slight discomfort in the intestines to a life-threatening shock caused by an over-eager immune system.
Theimmune system considers the intestine like outside the body, although it is firmly and clearly placed in the abdomen. It is considered a contact point with the outside world, because everything people eat and drink get into the intestine. That youThe face of risks, because people can consume bacteria, viruses, fungi and other harmful organisms along with things they want to eat. Many Galt in the intestine is designed to provide the first line of immune defense to avoid the entry of harmful organisms into the body.
