Qhov sib txawv tseem ceeb ntawm plasma thiab cov kua nruab nrab yog cov plasma yog cov kua dej uas cov qe ntshav thiab cov platelets tshem tawm thaum cov kua nruab nrab yog cov kua dej uas nyob ib puag ncig cov hlwb hauv lub cev.
Dej yog lub ntsiab ntawm cov kua hauv lub cev. Yog li, cov dej hauv lub cev tuaj yeem pom feem ntau hauv ob qhov chaw loj hu ua intracellular kua thiab extracellular kua. Intracellular kua nyob rau hauv lub hlwb thaum cov kua extracellular nyob sab nraum lub hlwb. Intracellular kua suav rau feem pua siab dua piv rau cov kua dej ntxiv. Ntawm qhov tod tes, cov kua dej extracellular muaj ob hom loj; ntshav plasma thiab cov kua dej interstitial. Ntawm lawv, ntshav plasma nyob rau ib feem me me piv rau cov kua nruab nrab.
Plasma yog dab tsi?
Plasma yog ib qho ntawm ob feem ntawm cov kua dej ntxiv. Yog li ntawd, ntshav plasma los yog ntshav ntshav yog cov kua uas muaj nyob rau hauv lub vascular system (ntshav circulatory system). Nws yog cov nplej straw xim kua uas circulates hauv cov hlab ntsha. Tsis tas li ntawd, los ntawm tag nrho cov ntshav ntim, plasma suav txog 55% ntim. Yog li, nws muaj cov hlwb sib txawv xws li cov qe ntshav thiab platelets, thiab lwm yam.
Daim duab 01: Plasma
Tsis tas li ntawd, nws muaj ntau yam yaj xws li oxygen, carbon dioxide, ntsev, amino acids, fatty acids, cov tshuaj hormones, thiab cov ntshav plasma proteins. Tsis tas li ntawd, peb tuaj yeem pom qhov sib txawv me me hauv cov concentration ntawm cations thiab anions hauv plasma dua li hauv cov kua nruab nrab. Tsis tas li ntawd, plasma ua raws li cov protein cia ntawm tib neeg lub cev. Tsis tas li ntawd, nws yuav pab tiv thaiv lub cev los ntawm kev kis kab mob thaum khaws cov electrolytic tshuav nyiaj li cas.
Dab tsi yog Interstitial Fluid?
Interstitial kua yog qhov tseem ceeb thib ob ntawm cov kua dej ntxiv. Yog li ntawd, nws nyob ib puag ncig tag nrho cov cell hauv ib lub cev. Hauv cov lus yooj yooj yim, cov kua dej interstitial yog cov kua dej uas cov hlwb submerged. Thaum piv rau cov ntshav plasma, cov kua dej interstitial occupies ntau feem pua ntawm cov kua dej extracellular. Tab sis thaum piv rau tag nrho cov kua hauv lub cev, cov kua nruab nrog cev tsuas yog 26%.
Daim duab 02: Cov kua dej sib xyaws
Feem ntau, vim qhov nyuaj ntawm kev sib cais, cov kua dej nruab nrab thiab cov qog ntshav tau muab tso rau hauv ib qho khoom. Yog li, cov kua dej interstitial tuaj yeem suav tias yog ultrafiltrate ntawm plasma. Ntxiv mus, cov kua dej interstitial yog cov ntaub so ntswg uas thauj cov khoom noj los ntawm cov ntshav mus rau cov hlwb, thiab carbon dioxide thiab lwm yam pov tseg rov qab mus rau cov ntshav los ntawm cov hlwb.
Dab tsi yog qhov zoo sib xws ntawm Plasma thiab Interstitial Fluid?
- Plasma thiab interstitial kua yog cov kua dej ntxiv.
- Lawv nyob sab nraum lub cev hlwb.
- Tsis tas li ntawd, ob hom suav nrog tsawg feem pua ntawm cov kua dej intracellular hauv peb lub cev.
- Tsis tas li ntawd, dej yog qhov tseem ceeb ntawm ob lub kua dej.
- Tsis tas li ntawd, ob lub kua dej no tseem ceeb heev rau kev ua haujlwm ntawm lub cev.
Qhov txawv ntawm Plasma thiab cov kua nruab nrab yog dab tsi?
Qhov sib txawv tseem ceeb ntawm plasma thiab cov kua nruab nrab yog cov plasma nyob hauv cov hlab ntsha thiab nws yog cov kua dej ntawm cov ntshav thaum cov kua nruab nrab nyob nruab nrab ntawm cov hlwb ntawm cov ntaub so ntswg. Lwm qhov sib txawv ntawm plasma thiab cov kua dej interstitial yog cov protein ntau. Ntawd yog, lub plasma muaj cov protein ntau dua li cov kua dej sib txuas. Txawm li cas los xij, los ntawm tag nrho cov ntim ntawm extracellular kua, interstitial kua suav rau feem pua siab dua cov ntshav.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm cov ntshav thiab cov kua nruab nrog cev kom ntxaws ntxiv.
Summary – Plasma vs Interstitial Fluid
Plasma thiab interstitial kua yog ob yam tseem ceeb ntawm extracellular kua nyob rau hauv peb lub cev. Lawv txawv ntawm cov kua dej intracellular vim lawv nyob sab nraum lub cev hlwb. Plasma yog cov kua dej ntawm cov ntshav. Nws yog xim daj daj daj. Cov qe ntshav thiab platelets raug tshem tawm hauv plasma. Yog li, nws muaj ntau dua concentration ntawm yaj oxygen. Ntawm qhov tod tes, cov kua dej interstitial yog cov kua uas nyob ib puag ncig thiab da dej tag nrho lub cev hlwb. Nws suav txog qhov feem pua ntawm cov kua dej extracellular ntau dua li cov ntshav plasma. Cov concentration ntawm cov pa yaj hauv cov ntshav yog tsawg dua piv rau cov ntshav ntshav. Yog li ntawd, qhov no yog qhov sib txawv ntawm plasma thiab interstitial kua.
