Dilation of afferent arteriole nce Pgc , vim ntau cov hlab ntsha siab tau xa mus rau glomerulus. Dilation ntawm efferent arteriole efferent arteriole Cov efferent arteriole yog cov hlab ntsha uas yog ib feem ntawm cov urinary ib ntsuj av. Efferent (los ntawm Latin ex + ferre) txhais tau tias "outgoing", hauv qhov no txhais tau tias nqa ntshav tawm ntawm lub glomerulus. https://en.wikipedia.org › wiki › Efferent_arteriole
Efferent arteriole - Wikipedia
nce Pgc vim tias ntau ntawm cov hlab ntsha siab tau xa mus rau glomerulus. Teb rau kev hloov siab ntawm nephron ntawm 90 thiab 180mm.
Yuav ua li cas yog tias afferent arteriole dilates?
Dilation of the afferent arteriole has pawg cuam tshuam. Constriction ntawm efferent arteriole ib leeg kuj txo RBF tab sis nrog kev nce hauv glomerular capillary siab. Qhov no ua rau muaj kev txheeb ze nce ntxiv hauv GFR dhau ntawm RBF, kom pom cov feem ntau ntxiv.
Dab tsi ua rau afferent arteriole dilate?
Afferent arteriole constriction ua rau txo GFR thiab txo RPF, ua rau tsis muaj kev hloov pauv hauv FF. Ib qho tseem ceeb ua haujlwm ntawm prostaglandinsyog kom nthuav tawm cov hlab ntsha afferent.
Hloov cov afferent thiab efferent arteriole cuam tshuam GFR li cas?
Ib nce hauv afferent arteriolar txoj kab uas hla(txo qis hauv qhov tsis kam) ua raunce hauv glomerular capillary hydrostatic siab thiab nce GFR. Kev txo qis hauv txoj kab uas hla ntawm afferent arteriole muaj qhov cuam tshuam. … Ib qho kev txo qis ntawm txoj kab uas hla ntawm cov hlab ntsha efferent muaj qhov cuam tshuam.
Yuav ua li cas rau GFR thaum lub efferent arteriole dilates?
nce ntshav ntim thiab nce ntshav siab yuav nce GFR. Constriction nyob rau hauv afferent arterioles mus rau hauv lub glomerulus thiab dilation ntawm efferent arterioles tawm ntawm lub glomerulus yuav txo GFR. Hydrostatic siab hauv Bowman's capsule yuav ua haujlwm kom txo GFR.
