Document Summary

I. outcomes: compare innate and acquired immunity, also compare passive and active, create a flow chart of counter current exchange in fish gills, compare and contrast gas transfer through skin, gills, and lungs. Give examples for each: trace oxygen and carbon dioxide through the respiratory system, and circulatory system from inhalation to exhalation. A. partial exerted by a particular gas in a mixture of gases. B. to calculate, you must know: pressure of mixture, fraction of specific gas in mixture. C. diffusion of gas: always from high partial pressure -> low partial pressure, if partial pressure is known, you can predict direction of flow. A. <1 mm thick: almost every cell in contact with environment. B. no specialized circulatory and respiratory systems: no transport systems, aerobic cellular respiration. C. exchange via simple diffusion: o2 diffuses from h2o into organism, co2 diffuses from organism into h2o. A. large organisms: larger than ~ 1mm thick.
