The innate immune response

Phagocytosis is a mechanism of the innate insubordinate reception. Describe trine cells who be responsible for phagocytosis and describe what triggers each to respond. Describe how two other aspects of the repellent response can stir phagocytosis. What military group do scavenger cells play in initiating the reconciling tolerant response?         The innate immune response reduces the workload of the adaptive immune response by preventing entry and spread of microorganisms in the body. The branch line of defense is the external body tissue layer - total skin and mucosae. The second line of defense is c solelyed into action when the starting time line of defense has been penetrated, exploitation antimicrobial proteins and phagocytes. A phagocyte engulfs matter the way an amoeba ingests a food particle. Three cells that ar responsible for phagocytosis be monocytes, neutrophils, and eosinophils. The major phagocytes ar macrophages, which deriv e from fresh blood cells called monocytes that go out the bloodstream, enter the tissues, and develop into macrophages. When chemicals released by immune cells stimulate them, sp atomic number 18 enzymes are activated that produce the respiratory burst, an event that liberates a flood of free radicals that have unbendable cell-killing ability. Monocytes take some 12 hours to differentiate and there are a chaw of them. Neutrophils become phagocytic on merginging pathogenic materials in the tissues. Neutrophils are small but numerous and plus during acute transmission system (especially bacterial), secreting enzymes and producing antibiotic-like chemicals called defensins, that pierce the pathogens membrane and destroy the neutrophils in the process. Eosinophils are sapless phagocytic and are fewer, but they are important in defending the body against parasitic worms. When they encounter parasitic worms, the eosinophils barrage the contents of their large cytoplasmic granules all over their prey. deuce other a! spects of the immune response that can enhance phagocytosis are adherence and opsonization.
