Qhov sib txawv tseem ceeb ntawm vasa recta thiab peritubular capillaries yog vasa recta yog hom tshwj xeeb ntawm peritubular capillaries uas muab cov pa oxygen thiab cov as-ham rau medulla ntawm lub raum thaum peritubular capillaries yog cov capillaries uas tshwm sim los ntawm efferent arteriole thiab pub. lub raum nrog oxygen thiab cov as-ham.
Lub raum yog lub cev uas lim ntshav thiab tshem tawm cov khoom pov tseg ntawm lub cev los ntawm cov zis. nephron yog lub luag haujlwm tseem ceeb ntawm lub raum. Muaj ob txoj hlab ntsha tuaj thiab mus los ntawm glomerulus ntawm nephron. Lawv yog afferent arteriole thiab efferent arteriole. Tsis tas li ntawd, ib qho efferent arteriole tau muab faib rau hauv cov kab mob capillary hu ua peritubular capillaries. Tsis tas li ntawd, vasa recta yog hom tshwj xeeb ntawm peritubular capillaries uas muab cov as-ham thiab oxygen rau medulla ntawm lub raum.
Vasa Recta yog dab tsi?
Vasa recta yog hom tshwj xeeb ntawm peritubular capillaries uas pub medulla ntawm lub raum nrog oxygen thiab cov as-ham. Lawv tshwj xeeb tshwm sim los ntawm efferent arteriole ntawm juxtamedullary nephrons thiab cua ncig lawv Henle loops. Tsis tas li ntawd, lawv tsim ib qho kev sib txuas ntawm hairpin loops hauv medulla. Vasa recta yog permeable heev rau solute thiab dej.
Daim duab 01: Vasa Recta
Ntxiv rau kev muab cov as-ham rau medulla ntawm lub raum, vasa recta ua lwm txoj haujlwm. Vasa recta pab tshem tawm cov dej thiab cov kua dej ntxiv rau hauv medullary interstitium los ntawm nephron.
Peritubular Capillaries yog dab tsi?
Peritubular capillaries yog cov kab mob capillary uas tshwm sim los ntawm cov hlab ntsha uas tawm los ntawm lub glomerulus. Peritubular capillaries muab cov as-ham thiab oxygen rau lub raum cortex. Yog li ntawd, ib feem loj ntawm peritubular capillaries yog nyob rau hauv lub raum cortex. Lawv nyob ib puag ncig cov tubules uas nyob ze thiab deb.
Daim duab 02: Peritubular Capillaries
Tsis tas li ntawd, tshwj xeeb peritubular capillaries hu ua vasa recta ncig Henle loops ntawm juxtamedullary nephrons. Cov capillaries no pab txhawb cov reabsorption ntawm cov khoom tseem ceeb xws li qabzib, amino acids, ions, minerals thiab dej, thiab lwm yam, rov qab mus rau cov ntshav los ntawm cov lim dej. Thaum kawg, cov ntshav ntawm peritubular capillaries tawm hauv lub raum los ntawm lub raum leeg.
Dab tsi zoo sib xws ntawm Vasa Recta thiab Peritubular Capillaries?
- Vasa recta yog hom tshwj xeeb ntawm peritubular capillaries.
- Lawv nyob hauv lub raum.
- Tsis tas li ntawd, lawv tshwm sim los ntawm cov hlab ntsha efferent.
- Ob leeg muab cov as-ham thiab oxygen rau lub raum.
- Ntxiv mus, lawv pab txhawb cov reabsorption ntawm cov khoom muaj txiaj ntsig rov qab mus rau cov ntshav los ntawm glomerular filtrate.
Qhov txawv ntawm Vasa Recta thiab Peritubular Capillaries yog dab tsi?
Vasa recta yog cov me me capillaries uas nyob ib puag ncig Henle loops thiab muab cov as-ham thiab oxygen rau lub raum medulla thaum peritubular capillaries yog cov capillaries uas nyob ib puag ncig cov tubules ze ze thiab deb thiab muab cov as-ham thiab oxygen rau lub raum cortex. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm vasa recta thiab peritubular capillaries.
Summary – Vasa Recta vs Peritubular Capillaries
Vasa recta yog ib hom tshwj xeeb ntawm peritubular capillaries uas nyob ib puag ncig Henle loops ntawm juxtamedullary nephrons thaum peritubular capillaries yog cov capillary network tshwm sim los ntawm efferent arteriole. Qhov no yog qhov sib txawv tseem ceeb ntawm vasa recta thiab peritubular capillaries. Lub raum cortex muaj ib feem loj ntawm peritubular capillaries thaum lub raum medulla muaj vasa recta.
