Angiotensin II yog tsim systemically thiab hauv zos hauv ob lub raum . Nws constricts afferent thiab efferent arterioles∗ thiab txo RBF thiab GFR.
Angiotensin nyob qhov twg?
Angiotensinogen yog tsim nyob rau hauv lub siab thiab pom tsis tu ncua ncig hauv cov ntshav. Tom qab ntawd Renin ua haujlwm txhawm rau txhawm rau angiotensinogen rau hauv angiotensin I. Angiotensin I yog lub cev tsis muaj zog, tab sis ua haujlwm ua ntej rau angiotensin II.
Qhov twg hauv lub cev yog angiotensin II tsim?
Angiotensin II yog tsim los ntawm cov txheej txheem thiab hauv zos hauv ob lub raum . Nws constricts afferent thiab efferent arterioles∗ thiab txo RBF thiab GFR.
Qhov twg ntawm angiotensin II yog dab tsi?
Liver Angiotensinogen Yog thawj qhov chaw ntawm lub raum Angiotensin II.
YPuas angiotensin II tsim hauv lub ntsws?
Angiotensin-hloov enzyme (ACE) plays lub luag haujlwm tseem ceeb hauv kev tsim cov tshuaj angiotensin II los ntawm angiotensin I, thiab cov hlab ntsha capillary hauv lub ntsws yog ib qhov chaw loj ntawm ACE qhia thiab angiotensin II ntau lawm hauv tib neeg lub cev.
