PPT-Immunity Innate and Adaptive Immunity

Cells of the Immune System Physical amp Chemical Barriers Innate and Adaptive Immunity Innate Defenses Nonspecific physical and chemical barriers that contribute to resistance against infection. Adaptive (specific) Immunity. The general idea:. body . can recognize . specific. . invader and act to destroy . that specific invader.. Adaptive . immunity develops during an individual. ’. s lifetime.. Present before exposure to pathogens. Present at birth. Non-antigen specific. Consists of:. Skin… barrier for microbes and viruses. Compromised by abrasion or laceration. Sebacious. sweat is acidic (pH 3-5)… prevents colonization of bacteria. Clarence Lam, . Sanket. Patel, . Tairan. Yang, Narthaanan Srimurugathasan.

Year 10 Science Life - psychology. A behaviour is . any observable action. made by a living . person. Examples . include; walking, crying, blinking, eating . etc.. All . of these activities can be . E . Wolf decoy for geese (plenty in New England).. Why are these decoys efficient?. Geese do not have pictures to teach their young ones what animals to avoid…. … and so they must be born with images of predators engraved in their brain. Adaptive (specific) Immunity. The general idea:. body . can recognize . specific. . invader and act to destroy . that specific invader.. Adaptive . immunity develops during an individual. ’. s lifetime.. All organisms have innate behaviors that are inherited from parents that develop independently from the environment. Innate behavior is inherited from an individual’s parents and is not modified by the individual and is generally not affected by the organism’s environment, including an organism’s experiences.. Chapter 16: Innate (nonspecific) Immunity. Some terms:. Susceptibility. : Lack of immunity to a disease.. Immunity. : Ability to ward off disease.. . . immunity. : Defenses against any pathogen.. Chaparral High School. What is immunology?. Very simply, it is the study of our body’s defense against infection and disease.. Even though we are constantly bombarded by microorganisms, we rarely become sick. Why?. Learning objectives. By the end of this session student will be able to. .
