BIOL 1002 : Test 3 Notes
Document Summary
What are barrier defenses: figure 36-1, vertebrae have three major lines of defense against disease, nonspecific defenses. If swallowed, they enter the stomach where protein-digesting enzymes and acidity is lethal to them: the intestines contain bacteria that, while harmless to humans, secrete substances that destroy invading bacteria or fungi. In the urinary tract, the slight acidity of urine inhibits bacterial growth. Describe the inflammatory response: figure 36-4 on test, attracts phagocytes to infected or injured tissue, symptoms: It initiates protective behavior by causing pain: warm, red, swollen, painful, acts as a protective mechanism. What is humoral vs. cell-mediated immunity: type of specific internal defenses (aka adaptive immune response) Name and define each form of immunoglobulins. Contrast active and passive immunity: active immunity, passive. Describe various outcomes as a result of disrupting immunity. What are target cells: cells that contain a receptor, hormones may have more than one target cell, similar to the effector cell.
