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

Nyob hauv cov hlab ntsha hauv fetus nyob qhov twg cov pa oxygen?
Tsib tsib caug tsib feem pua ntawm cov fetal cardiac tso tawm mus los ntawm cov hlab ntsha umbilical umbilical artery umbilical hlab ntsha yog qhov kawg ntawm cov hlab ntsha sab hauv iliac (anterior faib ntawm). Cov no muab cov ceg qab qab nrog cov ntshav thiab cov as-ham hauv fetus.
Leej twg cov hlab ntsha nqa cov ntshav oxygenated?
Cov hlab ntsha nqa cov ntshav oxygenated los ntawm lub plawv , thaum cov hlab ntsha nqa cov ntshav uas tsis muaj oxygen rov qab mus rau lub plawv. Ib qho yooj yim mnemonic yog "A rau 'artery' thiab 'tawm' (los ntawm lub plawv). (Cov kev zam rau txoj cai dav dav no yog cov hlab ntsws pulmonary hlab ntsha pulmonary ncig pumps deoxygenated ntshav los ntawm pulmonary artery.
Leej twg kos cov roj ntsha hauv cov hlab ntsha?
Yuav Ua Li Cas Kos ABG. Cov Ntshav Ntshav Ntshav yuav tsum tus kws saib xyuas neeg mob txhawm rau sau cov qauv me me ntawm cov ntshav - feem ntau, tag nrho 1 ml³ nyiam dua. Cov ntshav tuaj yeem kos los ntawm cov hlab ntsha ntawm lub dab teg, puab tais, lossis saum lub luj tshib.
Cov hlab me me tshaj plaws nyob rau hauv cov hlab ntsha hu ua qhov twg?
Cov hlab ntsha me tshaj plaws, hu ua capillaries, me me heev koj xav tau lub tshuab ntsuas kom pom lawv. Capillaries koom ua cov hlab ntsha loj. Qhov loj dua yog hu ua cov leeg. Cov hlab no nqa ntshav rov qab mus rau lub plawv . Cov hlab ntsha me tshaj plaws lossis cov hlab ntsha hauv cov hlab ntsha yog dab tsi?
Qhov twg ntau dua ntawm qhov kawg ntawm cov hlab ntsha?
Capillary Hydrostatic Pressure (P C ) 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?
