{Identify the tubular structure in image A? - collecting duct - efferent arteriole + proximal convoluted tubule - loop of henle - distal convoluted tubule
 * type=""}

{Identify the tubular structure in image b? + collecting duct - efferent arteriole - proximal convoluted tubule - loop of henle - distal convoluted tubule
 * type=""}

{Which of the following are mechanisms that result in INCREASED blood pressure? + reduction in glomerular flow rate by mesangial cells - reduction in aquaporin channels in collecting ducts - decreased permeability in - decrease in aldosterone release from the adrenal cortex - decreased sodium uptake from the distal convoluted tubules
 * type=""}

{Identify the correct statement about renin secretion and function - Renin secretion from the adrenal cortext increases sodium uptake from the distal convoluted tubules - Renin secretion from mesangial cells increased glomerular flow rate + Renin secretion from juxtaglomerular cells activates angiotensin II and increased blood pressure - Renin secretion in the loop of Henle decreases Na+ permeability in the collecting ducts - Renin secretion from podocytes increases endothelial fennestration size, thereby increasing protenuria
 * type=""}

{The following structures are components of the renal cortex EXCEPT: - glomerulus - macula densa - urinary space + papillary ducts - collecting ducts
 * type=""}
