Qhov sib txawv tseem ceeb ntawm osmosis thiab kev lim ntshav yog tias osmosis yog hais txog kev txav ntawm cov dej los yog cov kuab tshuaj molecules los ntawm qhov chaw siab mus rau qhov chaw tsis tshua muaj siab los ntawm cov khoom siv semi-permeable thaum lub dialysis yog hais txog cov txheej txheem ntawm kev sib cais cov kuab tshuaj molecules. nyob rau hauv ib qho kev daws los ntawm qhov sib txawv ntawm lawv cov diffusion tus nqi los ntawm ib tug semi-permeable membrane.
Diffusion, osmosis, dialysis, thiab nquag thauj, thiab lwm yam yog cov txheej txheem uas piav qhia txog kev txav ntawm cov molecules ntawm ib cheeb tsam mus rau lwm qhov chaw. Qee qhov kev txav mus los xav tau lub zog txaus thaum qee qhov tshwm sim tsis muaj zog. Thaum cov molecules txav los ntawm ntau dua concentration mus rau qis concentration, nws tsis siv zog. Txawm li cas los xij, thaum muaj qhov sib txawv txav tshwm sim; cov molecules txav los ntawm qhov chaw tsis tshua muaj siab mus rau qhov chaw siab concentration, cov txheej txheem siv lub zog vim nws yuav siv qhov chaw tiv thaiv cov concentration gradient. Cov kev txav no yog qhov tseem ceeb txhawm rau txhawm rau lim cov tshuaj, tswj kev sib npaug ntawm osmosis, txav ions thiab lwm yam khoom nyob rau hauv thiab tawm thoob plaws lub cell daim nyias nyias, thiab lwm yam. Ntawm qhov sib txawv txav, osmosis thiab dialysis yog ob txoj haujlwm tseem ceeb. Tsis tas li ntawd, ob qho tib si osmosis thiab lim ntshav muaj ob hom; endosmosis thiab exosmosis yog ob hom osmosis, thiab ob hom kev lim ntshav tseem ceeb yog hemodialysis thiab peritoneal dialysis.
Osmosis yog dab tsi?
Osmosis yog ib hom kev sib kis uas cov dej molecules lossis cov kuab tshuaj molecules txav los ntawm thaj chaw siab dua mus rau thaj tsam qis qis los ntawm cov ntaub ntawv semi-permeable. Cov txheej txheem no txuas ntxiv mus kom txog thaum lub ntsiab lus sib npaug sib npaug hauv ob qho tib si.
Txawm li cas los xij, hauv osmosis, cov khoom siv semi-permeable tsis tso cai rau cov kua nplaum txav mus hla daim nyias nyias. Txij li cov dej molecules los yog cov kuab tshuaj molecules txav raws qhov concentration gradient, nws tsis xav tau lub zog. Li no, nws yog txheej txheem passive uas tshwm sim spontaneously.
Daim duab 01: Osmosis
Osmosis yog ib qho tseem ceeb ntawm cov txheej txheem lom neeg mus rau hauv lub hlwb ntawm tag nrho cov nroj tsuag thiab tsiaj txhu. Qhov tseeb, nws yog thawj txheej txheem uas cov dej thauj mus rau hauv thiab tawm ntawm cov hlwb.
Dialysis yog dab tsi?
Dialysis yog txheej txheem uas cais cov kuab tshuaj hauv cov tshuaj raws li lawv qhov diffusion. Nws kuj tshwm sim los ntawm ib tug semi-permeable membrane. Solutes txav los ntawm ntau dua concentration mus rau qis concentration raws li cov concentration gradient los ntawm ib tug xaiv membrane. Dialysis feem ntau yog siv los pab cov neeg mob uas raug kev txom nyem los ntawm lub raum tsis ua haujlwm vim lawv lub raum tsis tuaj yeem ua kom cov ntshav huv ntawm lawv tus kheej. Yog li, kev lim ntshav tuaj yeem ua tau txhawm rau txhawm rau kho lub raum tsis ua haujlwm, tshem tawm cov tshuaj, co toxins, tshuaj lom ntawm peb lub cev, thiab lwm yam.
Daim duab 02: Dialysis
Kev lim ntshav muaj ob hom tseem ceeb. Hemodialysis yog ib hom, thiab nws siv lub tshuab hu ua dialyzer. Hauv hemodialysis, ntshav los ntawm cov hlab ntsha ntawm tus neeg mob mus rau lub tshuab (lub raum cuav). Tom qab ntawd lub tshuab tshem tawm cov impurities thiab cov khoom pov tseg ntawm cov ntshav thiab ntxuav cov ntshav. Thaum kawg, cov ntshav purified muab rov qab rau cov hlab ntsha ntawm tus neeg mob. Peritoneal dialysis yog lwm hom kev lim ntshav uas tsis siv lub tshuab, es tsis txhob, siv lub hnab ntim ntawm lub plab (peritoneum), thiab cov tshuaj ntxuav tes hu ua dialysate los ntxuav cov ntshav.
Dab tsi yog qhov zoo sib xws ntawm Osmosis thiab Dialysis?
- Osmosis thiab lim ntshav piav qhia txog kev txav ntawm cov molecules hla ib nrab permeable
- Lawv yog hom diffusion.
- Nyob rau hauv ob txoj kev, molecules txav los ntawm qhov chaw siab concentration mus rau qhov chaw qis concentration.
- Tsis tas li, ob qho tib si yog cov txheej txheem passive.
- Tsis tas li ntawd, ob qho tib si tshwm sim txuas ntxiv mus txog thaum nws mus txog qhov sib npaug.
Qhov txawv ntawm Osmosis thiab Dialysis yog dab tsi?
Osmosis yog kev txav ntawm cov dej hla ib daim nyias nyias nyias thaum lub dialysis yog lub zog ntawm cov kua dej molecules hla ib daim nyias nyias. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm osmosis thiab lim ntshav. Ntxiv mus, osmosis sib npaug ntawm cov ntsiab lus nyob rau hauv ob sab thaum dialysis cais cov kua dej me me los ntawm cov kua dej loj dua. Raws li, osmosis pab txhawb kev txav ntawm cov dej hauv thiab tawm ntawm cov hlwb thaum lub tshuab lim ntshav pab kom huv huv cov ntshav thiab tshem tawm cov khib nyiab thiab co toxins hauv cov neeg uas raug mob raum tsis ua haujlwm. Yog li, qhov no qhia txog lwm qhov sib txawv ntawm osmosis thiab lim ntshav.
Tsis tas li ntawd, osmosis muaj ob hom; uas yog, endosmosis thiab exosmosis thaum lim ntshav muaj ob hom tseem ceeb xws li hemodialysis thiab peritoneal dialysis. Tsis tas li ntawd, muaj qhov sib txawv ntawm osmosis thiab kev lim ntshav raws li lawv cov kev txav thiab. Cov ntsiab lus ntxiv tau nthuav tawm hauv infographic ntawm qhov sib txawv ntawm osmosis thiab lim ntshav
Summary – Osmosis vs Dialysis
Osmosis thiab lim ntshav yog ob txheej txheem uas cuam tshuam rau kev txav ntawm cov molecules hla ib daim nyias nyias. Nyob rau hauv osmosis, dej molecules los yog hnyav molecules txav los ntawm ntau dua concentration mus rau tsawg concentration raws lub concentration gradient los ntawm ib tug semi-permeable membrane. Ntawm qhov tod tes, hauv kev lim ntshav, me me solute molecules cais los ntawm cov kuab tshuaj loj dua los ntawm kev txav los ntawm cov concentration siab dua mus rau qis dua ntawm cov khoom siv semi-permeable. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm osmosis thiab lim ntshav.
Tsis tas li ntawd, osmosis tuaj yeem yog endosmosis lossis exosmosis thaum kev lim ntshav tuaj yeem yog hemodialysis lossis peritoneal dialysis. Osmosis yog ib hom diffusion uas tshwm sim passively. Ntawm qhov tod tes, kev lim ntshav tuaj yeem tshwm sim los ntawm diffusion lossis pom. Tag nrho cov ntaub ntawv hais los saum toj no qhia txog qhov sib txawv ntawm osmosis thiab lim ntshav.
