How much CO does the kidney receive?
How much kidney filtrate formed/day?
Does the SNS constrict or relax the renal system?
What is the function of AngII?
Constrict efferent/afferent arterioles
****Efferent more affected
What drives GFR?
What is the range of MW for molecules that can and can't pass the glomerulus?
MW 7000 - 70,000
Can a negative ion pass the glomerulus?
No, due to negative charged diaphragm
Does AngII increase/decrease Kf? How?
Contracts Mesangial cells
What is the function of ANP, glucocorticoids, NO and prostaglandins?
Dilate Efferent/Afferent arteriole
GFR increases and causes more NaCl to be present at glomerulus
Macula Densa cells recognize increase in NaCl and signal
Signalling causes constriction of afferent arteriole
constriction of afferent arteriole causes GFR and RBF to decrease
What chemical constricts the afferent arterial in the Tubuloglomerular system?
