Qhov hluav taws kub yog qhov txaus ntshai, ua ntej ntawm txhua yam, vim nws qhov kev tswj tsis tau. Yog muaj nplaim taws sai sai mus thoob lub tsev lossis hla hav zoov, ces yuav luag tsis yooj yim. Qhov hluav taws kub tuaj yeem tshwm sim rau ntau yam, tib txoj kev los tiv thaiv nws yog kom ceev faj thaum tuav hluav taws, tab sis muaj xwm txheej thaum muaj hluav taws tshwm sim tsis muaj kev cuam tshuam los ntawm tib neeg.

Qhov hluav taws kub ua rau cov khoom siv tsis raug, thiab ua rau tib neeg muaj mob lossis tuag. Nov yog kev sib txuas ntxiv uas tuaj yeem tshwm sim nthawv los sis yog tshwm sim los ntawm kev txhob txwm los sis kev xaj phom. Hluav taws kub yog qhov nyuaj rau nres, tshwj xeeb tshaj yog nyob rau hauv qhib huab cua thiab cua hlob, thaum oxygen ntxiv rau qhov hluav taws kub thiab cua pab nthuav nws.

Cov hluav taws tuaj yeem yog qhov chaw lag luam thiab chaw lag luam. Kev kub nyhiab hauv tsev yog tshwm sim hauv vaj tse thiab vaj tse. Raws li txoj cai, nws tuaj yeem pib vim muaj qhov ua haujlwm tsis zoo hauv kev ua haujlwm ntawm lub tshuab hluav taws xob, roj av xau, kev tswj cov khoom siv hluav taws xob tsis raug cai (piv txwv, tso lawv tawm ntawm cov ntsaws ntsaws mus rau hauv lub qhov (socket)), ua haujlwm tsis zoo ntawm cov cuab yeej ua cua sov, lub txim taws lossis kub kub ntawm qhov cub ntawm txheej txheej phom, nrog rau kev ua haujlwm tsis zoo saib ntawm cov ntais ntawv thiab cov luam yeeb zoo heev.

Cov hluav taws hauv tsev tau sib kis los ntawm qhib qhov rais thiab qhov rooj, uas los ntawm cov dej ntws zoo heev ntawm huab cua thiab oxygen nkag. Tsis tas li ntawd, dhau los ntawm qhov cua xa hluav taws xob thiab cov tiaj nyob ze, hluav taws tau yooj yim kis mus rau cov chav nyob sib ze, yog tias ntsuas tau tsis tu ncua kom tua nws.

Ib qho hluav taws kub muaj hluav taws xob hauv cov nroj tsuag hauv chaw lag luam. Nws cov laj thawj yog: yuam kev ntawm kev tsim qauv thiab tsim vaj tsev, tsis ua raws li kev ntsuas hluav taws kev nyab xeeb los ntawm cov neeg ua haujlwm, ua txhaum kev thev naus laus zis thaum ua haujlwm (piv txwv, thaum vuam), tsis ua haujlwm ntawm cov khoom siv hluav taws xob, tsis saib xyuas hluav taws.

Kev sib kis ntawm cov hluav taws kev lag luam yog ua kom yooj yim los ntawm: lub siab siab ntawm cov khoom sib txuas hauv cov huab cua, muaj ntau ntawm cov khoom siv hluav taws xob thiab cov kua hauv chav lossis hauv cov chaw tso khoom, nrog rau lawv cov khoom tsis raug, qhib qhov rooj thiab qhov rai, ua haujlwm tsis zoo nyob ruaj ruaj (twj tua hluav taws).

Hluav taws tshwm sim thaum muaj peb yam tshwm sim:

• cov khoom siv hluav taws xob lossis cov khoom siv tau raws chaw;

• hluav taws, tshuaj lom neeg lossis hluav taws xob;

• muaj cov pa oxygen lossis lwm yam txheej txheem oxidizing uas ua kom cov txheej txheem txuas mus ntxiv.

Kev raug hluav taws xob tshwm sim thaum ib qho khoom siv lossis cov khoom siv tau raug rhaub mus rau qhov kub ntawm cov khoom siv tau, uas tsim cov pa roj carbon monoxide thiab ntau lub zog ntawm cov thermal.
