Key Difference – Perfusion vs Diffusion

Perfusion yog qhov tshwm sim uas cov kua dej ntws los ntawm cov hlab ntsha los yog cov lymphatic system mus rau lub cev lossis cov ntaub so ntswg. Feem ntau nws tau piav raws li, cov ntshav ntws mus rau lub txaj capillary ntawm cov ntaub so ntswg. Perfusion yog qhov tseem ceeb heev tom qab kev phais mob plawv kom tswj tau cov ntshav zoo rau cov ntaub so ntswg uas ib txwm tswj hwm los ntawm cov kws kho mob. Lub Yim Hli Krogh yeej qhov khoom plig Nobel xyoo 1920 los piav txog cov ntshav perfusion hauv cov leeg pob txha.

Diffusion yog ib lo lus dav dav uas tuaj yeem siv rau ntau lub sijhawm. Feem ntau nws yog hu ua kev txav ntawm cov khoom los yog nthwv dej los ntawm thaj tsam ntawm qhov siab dua mus rau thaj tsam ntawm qhov qis dua. Diffusion kuj tau piav qhia tias yog qhov kev txav mus los ntawm cov khoom raws li qhov concentration gradient. Tab sis nyob rau hauv cov nqe lus kho mob, diffusion feem ntau yog hais txog kev nthuav tawm ntawm cov pa roj ntawm alveolar capillaries. Hauv alveoli capillaries, oxygen yog diffused los ntawm alveoli mus rau ntshav; Ib yam li ntawd, carbon dioxide yog diffused los ntawm cov ntshav mus rau alveoli. Qhov sib txawv tseem ceeb ntawm perfusion thiab diffusion yog, perfusion yog cov ntshav ntws los ntawm qee qhov loj ntawm cov ntaub so ntswg nyob rau hauv ib chav tsev whereas, diffusion yog passive txav ntawm hais raws li ib tug concentration gradient (gas pauv nyob rau hauv alveoli).

Perfusion yog dab tsi?

Lo lus perfusion yog coined los ntawm Fabkis lo lus "perfuse", uas txhais tau tias "kho tshaj los yog dhau". Perfusion feem ntau hu ua cov dej ntws los ntawm cov hlab ntsha los yog cov kab mob lymphatic mus rau cov ntaub so ntswg lossis lub cev. Qhov no feem ntau yog xa mus rau cov ntshav ntws mus rau lub txaj capillary ntawm cov ntaub so ntswg. Txhua cov ntaub so ntswg tsiaj xav tau cov ntshav txaus rau lub neej noj qab haus huv. Mal perfusion ntawm nws ua rau mob xws li ischemia, kab mob plawv thiab cov hlab ntsha sib sib zog nqus. Cov kev ntsuam xyuas uas ib txwm ua los ntawm tus kws kho mob (cov kws kho mob lossis cov neeg ua haujlwm xwm txheej ceev), txhawm rau txheeb xyuas qhov txaus perfusion, yog ib feem tseem ceeb ntawm kev ntsuas tus neeg mob. Cov kev ntsuam xyuas suav nrog ntsuas lub cev xim ntawm daim tawv nqaij, qhov kub thiab txias, thiab lwm yam kev mob xws li, qhov tsos thiab cov capillary refill. Clinical perfusionists yog qee zaum cov kws tshawb fawb soj ntsuam lossis kws kho mob uas siv tshuab cardiopulmonary bypass tshuab thaum muaj kev phais plawv loj. Lawv ua lub luag haujlwm tseem ceeb hauv lub plawv, lub siab thiab lub ntsws hloov pauv los ntawm kev pab tus neeg mob rov zoo.

Daim duab 01: Perfusion

Xyoo 1920, Lub Yim Hli Krogh yog thawj zaug piav qhia txog kev hloov pauv ntawm cov ntshav perfusion hauv cov leeg pob txha thiab lwm yam kabmob raws li qhov xav tau, los ntawm kev qhib thiab kaw cov hlab ntsha thiab cov hlab ntsha. Cov ntsiab lus, 'dhau perfusion' thiab 'hauv qab perfusion' hais txog qhov nruab nrab perfusion uas muaj nyob thoob plaws tag nrho cov ntaub so ntswg hauv ib tus neeg lub cev. Piv txwv li, lub plawv yeej ib txwm nyob rau hauv ntau perfusion vim nws cov dej num. Ntau cov qog kuj tseem nyob hauv lub xeev tshaj perfusion. Hypoperfusion tuaj yeem tshwm sim thaum cov hlab ntsha raug thaiv los ntawm ib qho embolus qhov twg me me lossis tsis muaj ntshav mus txog cov ntaub so ntswg. Txawm li cas los xij, hyperperfusion tuaj yeem yog vim muaj mob xws li mob. Perfusion feem ntau yog ntsuas los ntawm microspheres uas tau sau nrog cov xov tooj cua isotopes uas tau siv txij li xyoo 1960S'. Nws ntsuas cov hluav taws xob ntawm cov ntaub so ntswg txaus siab.

Diffusion yog dab tsi?

Diffusion yog piav raws li qhov nyiam ntawm cov molecules kis mus rau qhov chaw muaj nyob rau hauv thiaj li yuav nyob hauv qhov chaw tshwj xeeb. Gases thiab molecules nyob rau hauv cov kua yuav diffused los ntawm ib tug siab concentration ib puag ncig mus rau ib tug qis concentration ib puag ncig. Lub zog ntawm tes tsis yog siv rau kev nthuav tawm yog li, nws yog lub npe hu ua cov txheej txheem passive. Tsis tas li ntawd, nws yog tus kheej.

Daim duab 02: Diffusion

Ib tus lej ntawm cov txheej txheem tshwm sim nyob rau ntawm kev sib kis. Kev ua pa muaj feem cuam tshuam cov pa roj. Hauv lub ntsws, cov pa roj carbon dioxide diffuses tsim cov ntshav mus rau hauv huab cua ntawm lub ntsws alveoli. Cov pa oxygen yog diffused los ntawm huab cua mus rau hauv cov ntshav uas koom nrog cov qe ntshav liab. Diffusion kuj tshwm sim hauv cov nroj tsuag thaum cov txheej txheem photosynthesis tshwm sim. Qhov no feem ntau tshwm sim hauv cov nroj tsuag nplooj los ntawm kev sib pauv gaseous.

Dab tsi yog qhov zoo sib xws ntawm Perfusion thiab Diffusion?

  • Ob yam txheej txheem yog koom nrog hauv cov dej ntws.
  • Ob txoj kev tseem ceeb heev rau tib neeg txoj sia nyob.
  • Nyob rau hauv cov tsiaj, nyob rau hauv ob qho tib si lub circulatory system koom nrog thiab nws yog ib qho tseem ceeb rau cov txheej txheem no coj qhov chaw kom raug.

Summary – Perfusion vs Diffusion

Perfusion yog cov dej ntws los ntawm cov hlab ntsha los yog cov kab mob lymphatic mus rau lub cev lossis cov ntaub so ntswg. Feem ntau nws tau piav raws li cov ntshav ntws mus rau lub txaj capillary ntawm cov ntaub so ntswg (los ntawm lub plawv mus rau lub ntsws). Diffusion yog piav raws li qhov kev txav mus los ntawm cov khoom raws li qhov concentration gradient. Nws kuj tseem hu ua kev txav ntawm cov khoom los yog cov nthwv dej los ntawm thaj tsam ntawm qhov siab dua mus rau thaj tsam ntawm qhov qis dua. Qhov txawv ntawm perfusion thiab diffusion yog, perfusion yog cov ntshav ntws los ntawm qee qhov loj ntawm cov ntaub so ntswg hauv ib lub sijhawm, thiab ntawm qhov tsis sib xws, tes diffusion yog hais txog kev txav mus los ntawm cov khoom raws li qhov concentration gradient.
