Qhov sib txawv tseem ceeb ntawm endothelium thiab mesothelium yog qhov endothelium yog qhov yooj yim squamous epithelial cell txheej uas kab tag nrho cov hlab ntsha nrog rau cov hlab ntsha, lymph hlab ntsha thiab lub plawv thaum lub mesothelium yog qhov yooj yim squamous epithelial cell txheej uas kab. Cov kab mob loj hauv lub cev xws li peritoneum, pleura thiab pericardium.
Epithelium, mesothelium thiab endothelium yog peb hom cell txheej uas kab peb sab hauv nruab nrog cev, lub cev kab noj hniav thiab daim tawv nqaij. Yog li ntawd, lawv txhua tus yog kev tiv thaiv kev tiv thaiv ntawm lub cev. Structureally, mesothelium thiab endothelium yog tshwj xeeb los yog hloov cov txheej txheem epithelial nrog mesodermal keeb kwm. Raws li, lawv tau ua los ntawm cov kab mob squamous epithelial yooj yim. Ob leeg mesothelium thiab endothelium yog cov ntaub so ntswg ib txheej. Lawv kab qee qhov chaw sab hauv.
YEndothelium yog dab tsi?
Lub endothelium yog ib txheej nyias ntawm kev txhawb nqa cov ntaub so ntswg uas ua rau sab hauv ntawm cov hlab ntsha, cov hlab ntsha thiab lub plawv. Nws yog ib hom tshwj xeeb ntawm epithelium uas tsim cov kab mob squamous epithelial yooj yooj yim. Tsis tas li ntawd, nws muaj ib tug flattened cell txheej. Txij li thaum nws kab ntawm sab hauv ntawm lub circulatory system, nws muaj ncaj qha kev sib cuag nrog cov ntshav, lymph kua thiab circulating hlwb. Lwm yam tshaj li nyob rau hauv lub circulatory system, lub endothelium yog pom nyob rau hauv lub puab txheej ntawm lub cornea ib yam nkaus.
Daim duab 01: Endothelium
Zoo ib yam li mesothelium, endothelium muaj mesodermal keeb kwm. Tsis tas li ntawd, raws li cov txheej txheem ntawm tes hauv endothelium, nws tuaj yeem ua rau endothelium txuas ntxiv lossis fenestrated endothelium.
Mesothelium yog dab tsi?
Mesothelium kuj yog ib qho tshwj xeeb ntawm epithelium uas kab cov kab noj hniav loj ntawm lub cev xws li peritoneum, pericardium, mesentery, pelvis thiab pleura. Zoo ib yam li endothelium, nws yog cov ntaub so ntswg uas muaj mesodermal keeb kwm. Tsis tas li ntawd, nws muaj cov hlwb squamous epithelial teem rau hauv ib txheej txuas ntxiv.
Daim duab 02: Mesothelial Cells
Ntxiv mus, lub luag haujlwm tseem ceeb ntawm mesothelium yog kev tiv thaiv cov qauv sab hauv thiab pab txhawb kev txav thiab ua pa. Nws muab cov nplaum nplaum, tsis nplaum thiab tiv thaiv nto rau hauv cov qauv. Tsis tsuas yog kev tiv thaiv, tab sis mesothelial hlwb kuj tseem ceeb rau kev thauj cov kua thiab cov hlwb hla cov kab noj hniav, kev nthuav qhia antigen, o thiab kho cov ntaub so ntswg, coagulation thiab fibrinolysis thiab qog cell adhesion, thiab lwm yam.
Dab tsi zoo sib xws ntawm Endothelium thiab Mesothelium?
- Endothelium thiab Mesothelium yog cov txheej txheem tshwj xeeb ntawm cov cell epithelial uas kab qee qhov chaw sab hauv.
- Lawv muaj ib txheej cell.
- Kuj, ob leeg muaj mesodermal keeb kwm.
- Tsis tas li ntawd, ob qho tib si muaj cov hlwb squamous (cov hlwb nyias nyias).
Qhov txawv ntawm Endothelium thiab mesothelium yog dab tsi?
Endothelium thiab mesothelium yog ob hom ntaub so ntswg uas kab qee qhov chaw sab hauv. Endothelium kab lub circulatory system thaum lub mesothelium kab cov kab noj hniav loj lub cev. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm endothelium thiab mesothelium. Endothelium npog sab hauv ntawm cov hlab ntsha, lymph hlab ntsha thiab lub plawv thaum lub mesothelium npog peritoneum, pleura thiab pericardium.
Ntxiv mus, endothelium ua tiav cov haujlwm tseem ceeb suav nrog kev ua raws li kev tiv thaiv kev tiv thaiv, cuam tshuam nrog kev mob, ntshav txhaws, tsim cov qe ntshav, tswj ntshav siab, thiab lwm yam. Ntawm qhov tod tes, mesothelium muab cov nplaum nplaum, tsis yog nplaum. thiab kev tiv thaiv nto rau hauv cov qauv thiab lawv tseem yog ib qho tseem ceeb rau kev thauj cov kua thiab cov hlwb hla cov kab noj hniav, kev nthuav qhia antigen, o thiab kho cov ntaub so ntswg, coagulation thiab fibrinolysis thiab qog cell adhesion, thiab lwm yam. Li no, qhov no yog qhov sib txawv ntawm endothelium. thiab mesothelium.
Hauv qab infographic piav qhia qhov txawv ntawm endothelium thiab mesothelium hauv daim ntawv tabular.
Summary – Endothelium vs Mesothelium
Endothelium thiab mesothelium yog ob hom tshwj xeeb cov ntaub so ntswg uas tsim los ntawm cov txheej txheem squamous epithelial yooj yooj yim thiab kab qee qhov chaw sab hauv ntawm lub cev. Txawm li cas los xij, endothelium kab nyob rau sab hauv ntawm cov hlab ntsha, lymph hlab ntsha thiab lub plawv. Tab sis, mesothelium kab sab hauv ntawm lub cev kab noj hniav loj xws li peritoneum, pericardium thiab pleura. Yog li, qhov no qhia txog qhov sib txawv ntawm endothelium thiab mesothelium.
