Capillary Hydrostatic Pressure (PC) Lub siab no ua rau cov kua dej tawm ntawm lub capillary (piv txwv li, pom), thiab siab tshaj ntawm qhov arteriolar kawg ntawm capillary thiab qis tshaj ntawm venular kawg.
Qhov twg siab dua ntawm qhov kawg ntawm cov hlab ntsha?
lub siab osmotic yog siab dua ntawm qhov kawg ntawm venous tshaj nws nyob rau ntawm cov hlab ntsha kawg. Lub net filtration siab ntawm cov kua interstitial yog siab dua nyob rau hauv lub venous kawg tshaj li nyob rau hauv lub arterial kawg. Koj nyuam qhuav kawm 39 nqe lus!
Qhov twg ntau dua ntawm Venular kawg ntawm cov lus nug capillary?
Ntawm qhov kawg ntawm lub capillary, hydrostatic siab ntawm cov ntshavyog (siab dua, tsawg dua, tib yam li) osmotic siab ntawm cov kua nruab nrab. Ntawm qhov kawg ntawm cov hlab ntsha ntawm lub capillary, osmotic siab ntawm cov ntshav yog (siab dua, tsawg dua, tib yam li) hydrostatic siab ntawm cov kua dej interstitial.
Qhov twg ntau dua ntawm cov hlab ntsha kawg ntawm capillary hydrostatic siab lossis osmotic siab?
Ntawm cov hlab ntsha kawg ntawm cov hlab ntsha, capillary hydrostatic siab (CHP)yog siab dua cov ntshav colloid osmotic siab (BCOP), yog li cov kua txav tawm ntawm lub capillary (filtration). Nyob ze ntawm qhov chaw, CHP qis dua BCOP, yog li cov kua txav mus rau hauv lub capillary (reabsorption).
Yuav ua li cas thaum kawg ntawm lub capillary?
Ntawm qhov kawg ntawm lub txaj capillary, ntshav siab hauv lub nkoj tsawg dua li osmotic siab ntawm cov ntshav hauv lub nkoj. Cov txiaj ntsig tau tshwm sim yog tias cov kua dej, carbon dioxide thiab cov khoom pov tseg tau rub los ntawm lub cev nqaij daim tawv mus rau hauv cov hlab ntsha capillary.
