Document Summary

This system is involved in the uptake portion of vo2. Also involved in the removal of co2. Important in acid-base status lactic acid control (releasing co2 & h+) Air moved into lungs and warmed to 37 degrees celsius. Nasal cavity trachea lungs bronchi bronchioles alveoli. Alveoli are surrounded by a capillary bed. Interface b/w air in lungs and the blood stream. Tree like to increase surface area for maximal diffusion of o2 and co2. Flattened alveoli would take up half a tennis court 90 squared meter. Lungs and heart are suspended in a pleural sack (ie wrapped in saran wrap) Pleural membrane around lungs visceral pleura. Another pleural membrane exists on rib side parietal pleura. Lungs are extremely elastic always trying to shrink but cant due to vacuum. B/w these two membranes is a vacuum space known as the pleural space. Object goes through ribs and pleural membrane.
