Peb tuaj yeem hnov lawv tag nrho yog tias qee yam ntawm cov khoom molecules tuaj yeem nkag mus rau hauv lub xeev gaseous. Peb hnov ntxhiab tsw gases vim lawv cov molecules pub dawb nkag rau hauv peb lub qhov ntswg. Peb sem kuas vim qee qhov ntawm lawv cov molecules nkag mus rau theem roj tom qab khiav tawm ntawm cov kua nto.

tsw yog ua los ntawm?

Ntau cov ntxhiab tsw muaj organic compounds, txawm hais tias qee qhov sib xyaw yooj yim tsis muaj carbon, xws li hydrogen sulfide thiab ammonia, kuj tseem muaj.tshuaj tsw qab. Kev xaav ntawm cov ntxhiab tsw zoo yog txheej txheem ob kauj ruam. Ua ntej, muaj qhov physiological. Qhov no yog qhov kuaj pom ntawm stimuli los ntawm receptors hauv lub qhov ntswg.
