Autoregulation of Glomerular Filtration by Tubuloglomerular Feedback Helps Protect the Kidney

Multiple Choice

Autoregulation of glomerular filtration by tubuloglomerular feedback helps protect the kidney:

A) from rapid systemic arterial pressure variations that would otherwise cause large glomerular filtration rate changes.
B) from rapid systemic venous pressure variations that would otherwise cause large glomerular filtration rate changes.
C) by contracting the walls of the efferent arterioles, thus increasing systemic blood pressure.
D) by relaxing the walls of the efferent arterioles, thus reducing systemic blood pressure.
