Hauv kev ua pa sab nraud, oxygen diffuses hla cov pa ua pa los ntawm alveolus mus rau lub capillary, whereas carbon dioxide diffuses tawm ntawm lub capillary mus rau hauv lub alveolus.
oxygen diffuse mus rau hauv lub ntsws nyob qhov twg?
nqus pa nkag mus rau hauv lub ntsws thiab mus txog the alveoli. Cov khaubncaws sab nraud povtseg ntawm lub alveoli thiab cov hlab ntsha nyob ib puag ncig yog txhua tus tib lub xovtooj tuab thiab nyob ze rau ib leeg.
Yuav ua li cas thaum ua pa sab nraud hauv lub ntsws?
External Respiration Exchanges Gases nruab nrab ntawm lub ntsws thiab cov hlab ntshaInside the ntsws, oxygen yog pauv rau carbon dioxide pov tseg los ntawm cov txheej txheem hu ua kev ua pa sab nraud. Cov txheej txheem ua pa no tshwm sim los ntawm ntau pua lab lub hnab microscopic hu ua alveoli.
Dab tsi yog cov kauj ruam ntawm kev ua pa sab nraud?
Qhov peb yam tseem ceeb ntawm kev ua pa sab nraud yog thaj chaw ntawm lub alveolar membrane, ib nrab siab gradients ntawm gasses, thiab qhov sib txuam ntawm perfusion thiab qhov cua.
Qhov khoom ntawm kev ua pa sab nraud yog dab tsi?
txheej txheem no siv oxygen, thiab tsim carbon dioxide, nrog rau ntau lwm cov khoom pov tseg metabolites thaum lub sijhawm ua haujlwm ntawm cov hlwb. Cov tsiaj hauv dej nyiam pauv cov khoom pov tseg no los ntawm cov gills thaum lub sijhawm ua pa sab nraud nrog dej hauv lawv ib puag ncig.
