Innate immunity includes the anatomical barriers represented by the skin and mucous membranes which prevent pathogen entry, and the cellular barrier includes phagocytic cells like the macrophage, the body's scavenger which works alongside neutrophils and natural killer cells. Anatomical barriers include physical, chemical and biological barriers. The 'innate' or nonspecific immune system consists of natural anatomical barriers, macrophages, natural killer cells, neutrophils, and eosinophils. The skin and the surface of mucous membranes effectively prevent the entry. Such substances may have antimicrobial properties, low pH, or serve to breakdown or destabilize bacterial cells. Mucus saliva tears. Start studying Innate Immunity: Anatomical and Physical Barriers. PrenursingSmarterPro. The most important components of innate immunity are anatomical barriers, intact normal flora, tissue bactericides including complement, and ability to undergo inflammatory and phagocytic responses. The innate, or nonspecific, immune system is one of the two main immunity strategies (the other being the adaptive immune system) in vertebrates.The innate immune system is an older evolutionary defense strategy, relatively speaking, and is the dominant immune system response found in plants, fungi, insects, and primitive multicellular organisms (see Beyond vertebrates). Physiological barriers that contribute to the innate immunity are the body temperature, pH and various soluble secretory products of the mucosa. These barriers called anatomical barriers include the skin and the tissue surfaces connected to the body's openings called mucous epithelial layers (mucous membranes) that line the respiratory, gastrointestinal, and urogenital tracts along with the ducts of secretory glands.

The innate immune system has several first-line barriers to infection, preventing the entry and growth of pathogens.. Mucus saliva tears. These responses include physicochemical and anatomical barriers, e.g., respiratory tract-like enzymes, mucus or epithelial cells, as well as others that facilitate spore and hyphae clearance by the innate and adaptive immune system (Iwasaki, Foxman, & Molony, 2016). Anatomical Barriers of the Immune System. The epithelial surfaces form a physical barrier that is impermeable to most infectious agents, acting as the first line of defense against invading organisms. Epidermis consists of mostly dead cell filled with keratin. Physiological barriers include the actions of body structures (such as sneezing) or substances produced by tissues (such as tears and mucus) that reinforce the anatomical barriers. Anatomic Barriers - Innate and Adaptive Immunity. Skin and mucosa provide an effective immune barrier between the internal and external environment. Immune System's 3 Levels of Defence: 1) Anatomical and Physiological Barriers 2) Innate Response 3) Adaptive Response Anatomical Barriers 1) Intact Skin (tough, dead cells, oils) 2) Cilia and Mucus (trap pathogens and sweep them out of the throat) Physiological Barriers 1) Stomach Acid 2) Temperature (Fevers especially) Innate System - non-specific Innate immunity augments the protection offered by anatomical and physiological barriers.1The innate immune system relies upon a limited repertoire of receptors to detect invading pathogens, but compensates for this limited number of invariant receptors by targeting conserved microbial components that are shared by large groups of pathogens. The Anatomical Barriers of the Immune System There are two main parts of the immune system: the innate immune system, made up of anatomical barriers, and the adaptive immune system. Start studying Innate Immunity: Anatomical and Physical Barriers. Components of the innate immune system.
