The independence of renal blood flow from mean systemic aerial pressure is termed: 
Select and explain. 
A. Glomerulo-tubular balance, B. Distal tubule-glomerular feedback, C. Flow dependence of renal oxygen consumption, D. Autoregulation
D: Autoregulation
Answer: D: Autoregulation 
Explanation: This is the definition of autoregulation. Such regulation is independent of influences from outside the organ. It involves adjustments in the resistance at the afferent glomerular aeriole. Two processes are apparently involved in this regulation: myogenic control of the afferent aeriole and distal tubule-glomerular feedback.
