1. Types of immunity-e.g. innate, active, etc (ch 7 ,191)  Innate immunity includes two lines of defense: natural barriers and inflammation Natural barriers are physical, mechanical, and biochemical barriers at the body’s surfaces and are in place at birth to prevent damage by substances in the environment and thwart infection by pathogenic microorganisms.  the natural epithelial barrier and inflammation confer innate resistance and protection, commonly referred to as innate, native, or natural immunity. Inflammation associated with infection usually initiates an adaptive process that results in a long-term and very effective immunity to the infecting microorganism, referred to as adaptive, acquired, or specific immunity.  Adaptive immunity is relatively slow to develop but has memory and more rapidly targets and eradicates a second infection with a particular disease-causing microorganism.  Innate immunity includes two lines of defense: natural barriers and inflammation. Natural barriers are physical, mechanical, and biochemical barriers at the body’s surfaces and are in place at birth to prevent damage by substances in the environment and thwart infection by pathogenic microorganisms
