Document Summary
Innate: our immune system we are born with. First to bacteria shown in green: mast cells, that produces histamine that opens cells to let in other enzymes to help fight off bacteria. Vessels/glands that pick-up fluid, protein, lipids, etc. Contain wbcs that trap and destroy and filter pathogens. Another network that holds the white blood cells, lymph and other factors that help fight bacteria. Thymus produces t-cells, spleen: process dead debris after we fight a foreign invader, lymph nodes: swell up when there is an infection. White blood cells: on surveillance for infection, if you have an increase white blood cells (cid:271)e(cid:272)ause you are fighti(cid:374)g a(cid:374) i(cid:374)fe(cid:272)tio(cid:374), (cid:449)he(cid:374) it is lo(cid:449) it (cid:373)ea(cid:374)s you (cid:272)a(cid:374)"t fight off infection. The inflammatory response: following injury or infection inflammation occurs: Histamine causes blood vessels to dilate and fluid to accumulate. The immune system: two kinds of responses. Adaptive or acquired, over time you build your immune system from antigens.
