BIO 151 1st Edition Lecture 35 Outline of Last Lecture 1. Respiration: The Lung2. Control of breathingOutline of Current Lecture 1. Non-Specific Defense Mechanisms2. Inflammatory Response3. Active Immune Response4. AntibodiesCurrent Lecture - 4/23/15Non-specific defense mechanisms:- lines of defense, barriers- skin- both tears and saliva contain lysozymes- enzyme that makes holes in certain types of bacteria- phagocytes - white blood cells- monocytes - migrate into tissues and become macrophages- eosinophils - effective against parasitic worms that are too large to be ingested- antimicrobial proteins in the blood - complementInflammatory response:- response to physical injury or entry of microbes- dilating the capillaries increases the blood supply- swelling is due to plasma leakage- specificity- immune system produces antibodies that recognize foreign antigens- diversity among the immune system- self-nonself recognition- does not produce antibodies against its own molecules- memory cellsActive immunity:- generating of antibodies by an animal exposed to infection- vaccinated with dead cells that cannot produce disease- lets body see antigens and build up antibody response- passive immunity - antibodies made from one animal to another individual- anti-mediated immunity - molecules in blood interact with toxins and bacteria- cell-mediated immunity - molecule on outside of cellAntibodies:- antibodies recognize epitopes on antigenThese notes represent a detailed interpretation of the professor’s lecture.
