The jconduction jof jair jin jand jout jof jthe jbody jis jknown jas
jventilation. j Since j the j question j asks j for j the j body’s j mechanism,
jthis jwould jbe jspontaneous jventilation. jExternal jrespiration
jinvolves j the j exchange j of j oxygen j (O2) j and j carbon j dioxide
j (CO2) jbetween jthe jalveoli jand jthe jpulmonary jcapillaries.
jInternal jrespiration j occurs j at j the j cellular j level j and j involves
j movement j ofjoxygen jfrom jthe jsystemic jblood jinto jthe jcells.

ANS: j C
External j respiration j involves j the j exchange j of j oxygen j and
j carbonjdioxide j(CO2) jbetween jthe jalveoli jand jthe jpulmonary
jcapillaries. jInternal jrespiration joccurs jat jthe jcellular jlevel jand

ANS: jB
During j spontaneous j breathing j the j intrapleural j pressure
j drops jfrom j about j-5 jcm j H2O j at j end-expiration j to j about j-10

c. 0 jcm jH2O
d. 5 jcm jH2O
