Qhov sib txawv tseem ceeb ntawm kev nce thiab nqis ntawm lub voj voog ntawm Henle yog qhov nce mus txog ntawm Henle yog ntu tuab ntawm lub voj voog ntawm Henle nyob tom qab lub ntsej muag ntse ntawm lub voj thaum nqes voj ntawm Henle yog ntu nyias nyob ntawm qhov chaw xwb. ua ntej lub ntse khoov ntawm lub voj.

Lub nephron yog lub luag haujlwm tseem ceeb ntawm peb lub raum uas lim ntshav thiab tsim cov zis kom tshem tawm cov khoom pov tseg thiab cov kua dej ntxiv hauv lub cev. Nephron muaj ob qhov loj: lub raum corpuscle thiab lub raum tubule. Lub raum corpuscle muaj glomerulus thiab Bowman's capsule. Afferent arteriole nkag mus rau lub raum corpuscle nrog cov ntshav uas muaj cov khoom pov tseg thiab cov tshuaj tsis tsim nyog. Glomerulus lim dej thiab pov tseg rau hauv cov tshuaj ntsiav, tsis pub cov qe ntshav thiab cov molecules tsim nyog tawm hauv cov ntshav. Efferent arteriole tawm hauv glomerulus nrog lim ntshav.

Lub raum tubule pib los ntawm cov tshuaj ntsiav thiab thawj feem ntawm lub raum tubule yog proximal convoluted tubule. Tom qab ntawd ib qho chaw tshwj xeeb hu ua Henle voj khiav thiab nkag mus rau qhov thib ob ntawm lub raum tubule hu ua lub distal convoluted tubule. Cov tshuaj muaj txiaj ntsig tau rov qab nkag mus rau hauv cov ntshav los ntawm lub raum tubule thiab cov kua dej ntxiv tau tawm hauv lub cev raws li tso zis.

Ascending Loop of Henle yog dab tsi?

Ascending voj ntawm Henle yog ib qho ntawm ob feem ntawm lub voj ntawm Henle. Nws yog nyob tom qab lub ntse khoov ntawm lub voj, yog li nws yog qhov thib ob ntawm lub voj ntawm Henle. Nws txuas ntxiv mus rau qhov distal convoluted tubule thiab ntws cov kua dej los yog cov zis mus rau lub distal convoluted tubule.

Daim duab 01: Nephron

Muaj ob ntu ntawm lub voj voog ntawm Henle. Lawv yog nyias ascending limb thiab tuab ascending limb. Thick ascending limb yog thicker tshaj li nyias ascending limb. Nyias ascending limb yog qhov qis ntawm lub voj ascending ntawm Henle thiab nws yog lined los ntawm squamous epithelium yooj yim. Tick ascending limb yog sab sauv thiab nws yog lined los ntawm yooj yim cuboidal epithelium. Nws yog thawj qhov chaw rau sodium reabsorption.

Dab tsi yog Descending Loop of Henle?

Txog lub voj ntawm Henle yog thawj ntu ntawm lub voj ntawm Henle. Nws txuas nrog lub proximal convoluted tubule. Tsis tas li ntawd, nws yog ib feem ntawm lub raum tubule. Nyob rau hauv kev sib piv rau lub voj ascending ntawm Henle, lub voj descending ntawm Henle yog thinner.

Zoo ib yam li lub voj ascending ntawm Henle, lub voj descending ntawm Henle kuj muaj ob ntu, uas yog nyias thiab tuab. Tab sis lawv tsis txawv. Cov ceg nyias nyias yog kab los ntawm ib qho yooj yim squamous epithelium thaum lub ceg tuab yog kab los ntawm qhov yooj yim cuboidal epithelium. Lub epithelium ntawm lub voj descending ntawm Henle qhia tsis tshua muaj permeability rau ions. Tab sis nws yog permeable heev rau dej thiab nruab nrab permeable rau urea.

Dab tsi yog qhov zoo sib xws ntawm Kev nce thiab nqis qis ntawm Henle?

  • Ascending and descending loop of Henle is two part of the Henle loop of the nephron.
  • Lub voj ascending ntawm Henle yog ib qho kev txuas ncaj qha ntawm lub voj descending ntawm Henle.
  • Lawv belongs rau lub raum tubule.
  • Ob qho khoom muaj cov kua dej tubular.
  • Vasa recta khiav ncig ob qho tib si nce thiab nqis los ntawm Henle.
  • Re-absorption tshwm sim nyob rau hauv ob qho tib si ascending thiab descending voj ntawm Henle.
  • Ob qho tib si nce thiab nqis los ntawm Henle tsim U zoo li cov plaub hau zoo li tus qauv.

Dab tsi yog qhov txawv ntawm Ascending thiab Descending Loop ntawm Henle?

Ascending voj ntawm Henle yog ntu thib ob ntawm lub voj voog ntawm Henle thiab nyob tom qab lub ntsej muag ntse ntawm lub voj. Meanwhile, lub voj descending ntawm Henle yog thawj ntu ntawm lub voj ntawm Henle thiab yog nyob ua ntej lub ntse khoov ntawm lub voj. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev nce thiab nqis los ntawm Henle. Precisely, lub voj ascending ntawm Henle yog nyob nruab nrab ntawm lub voj descending ntawm Henle thiab distal convoluted tubule, thaum lub voj descending ntawm Henle nyob nruab nrab ntawm proximal convoluted tubule thiab ascending voj ntawm Henle.

Ntxiv mus, tus ceg nce toj yog tuab ntau dua li qhov nqis los. Yog li, qhov no yog qhov sib txawv ntawm qhov nce thiab nqis ntawm lub voj Henle. Cov kab ntawv hauv qab no qhia ntau cov ntsiab lus ntawm qhov sib txawv ntawm qhov nce thiab nqis los ntawm Henle.

Summary – Ascending vs Descending Loop of Henle

Lub voj ntawm Henle muaj ob ntu: lub voj nqes ntawm Henle thiab lub voj nce ntawm Henle. Lub voj voog ntawm Henle yog thawj qhov chaw nyob ua ntej lub ntsej muag ntse ntawm lub voj. Ascending voj ntawm Henle yog qhov thib ob uas nyob tom qab lub ntse khoov ntawm lub voj. Lub thickness ntawm lub voj ascending ntawm Henle yog siab tshaj qhov thickness ntawm lub voj descending ntawm Henle. Yog li, qhov no qhia txog qhov sib txawv ntawm qhov nce thiab nqis los ntawm Henle.
