WGU D115 patho-Unit 6 renal and urologic systems Questions & Answers

Autoregulation of renal blood flow - ANSWERprevents large changes in GFR when there are increases/decreases in BP; regulated neural and hormonal regulation renin-angiotensin-aldosterone system - ANSWER-decreased blood pressure causes the juxtaglomerular cells of kidneys to secrete renin which converts angiotensinogen (inactive) to angiotensin I (active) which is then converted into angiotensin II by angiotensin-converting enzyme (ACE) -Angiotensin II stimulates the adrenal cortex to secrete aldosterone - leads to absorption of Na and increased blood pressure -once blood pressure is restored, there is a decreased drive to stimulate renin release glomerular filtration - ANSWERthe movement of fluid and dilutes across glomerular capillary membrane into the Bowman space
