The Human Respiratory System ... Humans need a continuous supply of oxygen for cellular respiration, and they must get rid of excess carbon dioxide, the poisonous waste product of this process. Gas exchange supports the supports this cellular respiration by constantly supplying oxygen and removing carbon dioxide.

i.e., a contraction of the diaphragm, which is the driving force behind human respiration. Each breath a human takes is a result of the interaction described above. ... Human respiration is dependent upon the interaction of acetylcholine molecules with acetylcholine esterase receptors on the diaphragm muscle. Each time a...

Each of the pathways within respiration has been suspected of limiting maximal performance, suggesting that O2 transport may be affected by each single pathway. The use of the stable, isotopic O2 molecules 16O2 and 16O18O is presented as a novel method for assessing respiration.

The pattern of respiration may be differently changed by affecting cold receptors of different sites. Thus, the possibility of initiating the same effector response does not mean that these sensors are equal in their responses.
