Thiaj li, hydrostatic siab gradient heev kev nyiam sab nrauv lim ntawm cov dej thaum lub oncotic siab gradient kev nyiam sab hauv resorption ntawm dej.
Ib yam li ntawd, dab tsi quab yuam nyiam pom?
Txhawm rau xaus, raws li ib txwm muaj xwm txheej, nce hydrostatic siab hauv glomerulus nyiam lim dej, nce hydrostatic siab hauv Bowman qhov chaw tawm tsam pom, thiab nce oncotic siab nyob rau hauv lub glomerulus opposes pom zoo li thiab vice versa.
Ib sab saum toj no, lub zog twg tawm tsam kev lim dej glomerular? Cov zog uas kav lim hauv glomerular capillaries yog tib yam li txhua lub txaj capillary. Capillary hydrostatic siab (Pc) thiab Bowman qhov chaw oncotic siab (πi) nyiam lim rau hauv tubule, thiab Bowman qhov chaw hydrostatic siab (Pi) thiab capillary-oncotic siab (πc) tawm tsam pom.
Yog li ntawd, 4 Starling rog yog dab tsi?
lub zog yog:
- hydrostatic siab hauv capillary (Pc)
- hydrostatic siab hauv interstitium (Pi)
- oncotic siab nyob rau hauv capillary (pc)
- oncotic siab hauv interstitium (pi)
Tus nqi ntshav capillary yog dab tsi?
Glomerular cov hlab ntsha yog qhov paub ntau dua li glomerular pom tus nqi (GFR). Hauv seem ntawm lub cev cov hlab ntsha , feem ntau yog 5 ml / min (kwv yees li 8 litres / hnub), thiab cov kua dej rov qab mus rau kev ncig ntawm afferent thiab efferent lymphatics.
