Chapter 44 the immune system: internal defense. Immune responses (fig 44-1): body recognizes pathogens, toxins, other harmful agents and responds to eliminate them: Name the nonspecific immune mechanisms used by invertebrates. Nonspecific immune responses, include physical and chemical barriers; recognition by toll-like receptors; the actions of cells, such as phagocytes and natural killer cells; cytokines and the proteins that make up the complement system; and the inflammatory response. Physical barriers are a first line of defense the skin and saliva, respiratory and digestive tract linings, nose hairs, stomach secretions, lysosomes how is this so and provide some examples of each line of defense. Cytokines are signaling proteins and peptides that regulate interactions between cells. Interleukins are produced by macrophages and lymphocytes to help regulate interactions with other body cells. Summarize the steps in the inflammatory process Where are lymphocytes produce, where do they mature and where do they reside (are stored).
