Document Summary

Functions of the respiratory system: provides o2 to the blood removes co2 from the blood regulates [h+] (blood ph) speech. Microbial defense influences chemical messenger concentrations (e. g. ace) traps and dissolves small blood clots. *note: smoking causes the cilia to move out of coordination making it harder to get rid of foreign particles and thus increasing susceptibility to infection. Main function is gas exchange between air and blood terminal bronchioles of the conducting zone further branch into respiratory bronchioles of the respiratory zone. *alveoli are the sites of gas exchange with the surrounding capillaries note: alveoli is plural for alveolus note: no cartilage in the respiratory zone describe how co2 and o2 move across the blood gas barrier (bgb) Macrophages act as microbial defense in the respiratory zone. Pulmonary ventilation (ve) the volume of air entering the entire lung (both conducting and respiratory zones) in one minute.
