Qhov sib txawv tseem ceeb ntawm cov kua dej hauv nruab nrog cev yog cov kua hauv lub cev yog cov kua dej uas muaj nyob hauv cov hlwb, thaum cov kua nruab nrog cev yog cov kua nruab nrab ntawm cov hlab ntsha thiab cov hlwb.
Tib neeg lub cev kua tuaj yeem muab faib ua ntau yam kua dej. Ob lub ntsiab kua compartments yog intracellular thiab extracellular kua compartments. Cov kua dej intracellular yog qhov chaw nyob hauv cov hlwb ntawm tib neeg. Lub extracellular kua compartment yog sab nraum lub hlwb uas yog cais los ntawm intracellular kua compartment los ntawm cell membranes. Extracellular kua los yog compartment ntxiv faib ua peb hom: interstitial kua (ib puag ncig cell), intravascular kua (ntshav ntshav thiab lymph), thiab transcellular kua (ocular thiab cerebrospinal kua). Yog li ntawd, cov kua dej intracellular thiab interstitial yog ob hom kua hauv lub cev.
Dab tsi yog Intracellular Fluid?
Intracellular kua yog cov kua uas muaj nyob rau hauv lub hlwb. Nws muaj cytosol thiab kua hauv lub cell nucleus. Lub cytosol yog lub matrix uas cellular organelles raug tshem tawm. Cytosol thiab organelles ua ke ua lub cytoplasm. Cov kua dej ntawm cov nucleoplasm hauv lub cell nucleus hu ua nucleosol. Intracellular kua (ICF) muaj li ntawm 60% ntawm tag nrho cov dej nyob rau hauv tib neeg lub cev. Intracellular kua suav txog li 28 litres lossis 7.4 nkas loos dej. Cov kua ntim ntawm ICF zoo li ruaj khov heev. Qhov no yog vim hais tias cov dej nyob rau hauv cov hlwb nyob ze tswj.
Daim duab 01: Lub cev kua muag
Thaum cov dej hauv ib lub xovtooj poob mus rau qhov qis heev, cov cytosol yuav ua rau cov kua qaub ntau heev. Yog li ntawd, nws yuav nyuaj heev rau kev ua haujlwm ntawm tes. Ntawm qhov tod tes, yog tias dej ntau dhau mus rau hauv lub cell, lub cell yuav tawg thiab puas. Yog li ntawd, nyob rau hauv tej yam kev mob zoo tib yam, lub cell yog ib txwm nyob rau hauv osmatic equilibrium. Tsis tas li ntawd, nws muaj pes tsawg leeg ntawm magnesium thiab sulphate.
Dab tsi yog Interstitial Fluid?
Cov kua dej nruab nrab ntawm cov hlab ntsha thiab cov hlwb hu ua cov kua dej nruab nrab. Interstitial fluid, intravascular fluid, thiab transcellular fluid yog peb hom extracellular kua compartments. Lub interstitial kua compartment qee zaum hu ua cov ntaub so ntswg. Nws nyob sab nraum cov ntshav. Nws feem ntau nyob ib puag ncig cov ntaub so ntswg. Interstitial kua thiab ntshav plasma ua li 97% ntawm cov kua extracellular. Cov kua dej interstitial no tsis ruaj khov.
Daim duab 02: Cov kua dej sib xyaws
Hauv tib neeg lub cev, cov kua dej sib xyaw ua ke muaj 10.5 litres lossis 2.8 nkas loos kua. Nws muaj cov as-ham diffused los ntawm capillaries thiab cov khoom pov tseg tawm ntawm cov hlwb vim metabolism. Interstitial kua thiab plasma yog qhov zoo sib xws. Nws kuj muaj cov kuab tshuaj dej uas muaj suab thaj, fatty acids, amino acids, coenzymes, cov tshuaj hormones, neurotransmitters, qe ntshav dawb, thiab cov khoom pov tseg ntawm tes. Cov kua dej no suav nrog 26% ntawm cov dej hauv tib neeg lub cev. Tsis tas li ntawd, lub lymphatic system rov qab cov proteins thiab cov kua dej ntau dhau mus rau txoj kev ncig. Lub ionic compositing ntawm cov kua dej interstitial thiab ntshav ntshav sib txawv vim Gibbs- Donnan nyhuv.
Dab tsi zoo sib xws ntawm Intracellular thiab Interstitial Fluid?
- Intracellular thiab interstitial kua yog ob hom kua hauv lub cev.
- Ob lub kua dej muaj feem pua ntawm cov dej siab.
- Ob lub kua dej tsis muaj cov qe ntshav.
- Cov kua dej no muaj cov proteins.
- Cov kua dej no muaj cov khoom pov tseg.
Qhov txawv ntawm Intracellular thiab Interstitial Fluid yog dab tsi?
Intracellular kua yog cov kua uas nyob hauv hlwb. Hauv qhov sib piv, cov kua dej interstitial yog cov kua dej nyob nruab nrab ntawm cov hlab ntsha thiab cov hlwb. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov kua nruab nrog cev thiab cov kua nruab nrog cev. Tsis tas li ntawd, cov kua dej intracellular suav txog li 28 litres lossis 7.4 nkas loos dej, thaum cov kua nruab nrab suav txog li 10.5 litres lossis 2.8 nkas loos dej.
Cov hauv qab no infographic teev qhov sib txawv ntawm cov kua hauv nruab nrog cev thiab cov kua nruab nrab hauv daim ntawv.
Summary – Intracellular vs Interstitial Fluid
Cov kua hauv lub cev feem ntau yog ob hom ua kua hauv lub cev thiab cov kua dej ntxiv. Cov kua dej intracellular yog nyob rau hauv lub hlwb ntawm tib neeg. Extracellular kua yog sab nraum lub hlwb thiab yog cais los ntawm intracellular kua los ntawm cell membranes. Extracellular kua ntxiv tau muab faib ua peb hom: cov kua dej interstitial, kua dej intravascular, thiab cov kua dej transcellular. Yog li ntawd, cov kua dej uas pom nyob rau hauv cov cell hu ua intracellular kua. Ntawm qhov tod tes, cov kua dej ntawm cov hlab ntsha thiab cov hlwb hu ua interstitial kua. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm cov kua dej intracellular thiab interstitial.
