Document Summary

Questions: why does a stab wound to the chest cause the lung to collapse? a) b) the injury increases surface tension within the alveoli the intrapleural pressure increases. (to alleviate, go into chest cavity and draw out air between the two, pressure within the lung increases, surface tension within the alveoli increases, how is most carbon dioxide transported in the blood? a) by hemoglobin, as bicarbonate (even though co2 can be in blood, it is easier for bicarbonate to be transported by the blood, by surfactants, dissolved in plasma, which group is incorrect, pulmonary volumes: tidal, inspiratory reserve, expiratory reserve (doesn"t deal with residual volume, paranasal sinuses: frontal, maxillary, speroidal, ethmoidal, parts of the pharynx: oropharynx, nasopharynx, laryngopharynx, none of the above inspiratory volume extra air inspired expiratory volume last bit of air force exhaled tidal volume regular inspiration and expiration.
