BIO106 Study Guide - Quiz Guide: Programmed Cell Death, Humoral Immunity, Immunocompetence
Document Summary
What makes up the 1st line of defense? (two items) External body membranes (skin and mucosae): name 3 items in the 2nd line of defense. Immune system uses antibodies or complement proteins as opsonins that coat pathogens: define apoptosis. Fluid containing clotting factors and antibodies: briefly differentiate between humoral and cell-mediated immunity. Humoral immunity includes antibodies that circulate freely in body fluids and has extracellular targets. Immunocompetent b and t cells that are not yet exposed to antigens: what is the basic difference between the primary and second- dary immune response. A primary immune response is the exposure to an antigen for the first time and has a lag period of 3 to 6 days.
