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 kawg ntawm capillary yog ntshav siab dua?

Nyob hauv lub cev, Lub siab no yog siv los ntawm lub siab; Nws yog lub capillary ntshav siab. yog siab dua ntawm cov hlab ntsha kawg thiab ntog tsis tu ncua los ntawm cov hlab ntsha mus txog thaum ncav cuag tus nqi qis tshaj ntawm qhov kawg ntawm venous. siab=35-2=33 mmHg thawb kua tawm (filtration).

Puas venous siab ntau dua capillary siab?

Tus nqi ntawm R a/R v feem ntau yog 4 lossis ntau dua hauv lub cev, yog li capillary siab yog rhiab heev rau venous siab tshaj rau arterial pressure. Qhov no yog vim li cas venous congestion cuam tshuam rau kev pom tus nqi kom zoo heev (saib daim duab 9.3).

Lub siab twg yog siab tshaj ntawm qhov kawg ntawm lub capillary?

Lub siab no tsav cov kua dej tawm ntawm cov hlab ntsha (piv txwv li, pom), thiab siab tshaj plaws ntawm cov hlab ntsha kawg ntawm cov hlab ntsha thiab qis tshaj ntawm qhov kawg ntawm venular. Nyob ntawm lub cev, lub siab yuav poob raws qhov ntev ntawm lub capillary los ntawm 15-30 mmHg (axial lossis longitudinal siab gradient).

Yuav ua li cas rau ntawm qhov kawg ntawm lub venous capillary?

Ntawm cov hlab ntsha kawg ntawm capillary, hydrostatic siab tshaj oncotic siab, yog li cov kua txav tawm ntawm lub capillary mus rau hauv lub interstitial compartment. Thaum kawg ntawm lub venous capillary, ob lub zog tau thim rov qab, yog li cov kua txav rov qab los ntawm cov ntaub so ntswg mus rau hauv lub capillary
