Document Summary

Higher partial pressure to lower partial pressure in mixture of gases. 4 diffusion at thetissues where 02 movesfrom the bloodinto the tissues and co2fromthe tissue to the blood. 5 cellular respiration cells use of oz to produce energy and co2. 3 write out theequation of fick"s lawof diffusion. 4 explainhowfishgills are an example of countercurrent exchange explain why concurrent exchange is not efficient with fishgills. Fishgillsuse counter current exchange bloodflows inthe opposite direction to waterpassing over thegills. Blood is less saturated oz than in water so 02 from watermoves into the blood. In concurrent exchange diffusionwill eventually stop because concentration of oz will become equal. Human respiratory system consists the lungs and the circulatory system to transport gases between the lungs andthe restof the body. 6 know the pathway of air through the human respiratory system pharynx trachea is effectivefor gas exchange. 1 alveoli and capillaries are one celllayer thick. 3 large partial pressure difference between the alveoli and capillaries.
