Chapter 22. Functions of the Immune System. Destroy pathogens (organisms that cause disease). Detect and kill abnormal cells such as cancerous cells. Remove dead cells and debris from the body. Pathogens. The Body’s Defenses. Nonspecific Defenses Against Infection. The skin and mucous membranes provide first-line barriers to infection. -skin prevents the entry of pathogens. - mucous membranes line digestive and respiratory tracts. A. The body has two main mechanisms of defenses. 1. Innate defense mechanisms – first line of defense. A) These defenses are non-specific and . inherited. Immunity Overview.
