Renal Physiology - Part 2
The kidneys are of outstanding importance. They perform a number of homeostatic functions including filtration of plasma and elimination of metabolic waste products, regulation of the composition and volume of the extracellular fluid, and regulation of blood pressure. The kidneys are also endocrine organs. Test your basic knowledge of renal physiology by taking this simple quiz.
(1)   Approximately, how many nephrons are there in both human kidneys combined?
(2)   The hydrostatic blood pressure in the renal glomerular capillaries is approximately:
(3)   These kidney cells have foot-like processes that wrap tightly around the glomerular capillaries:



(4)   The cells of this region of the nephron distal tubule make close contact with afferent and efferent arterioles of the same nephron:



(5)   In the presence of the antidiuretic hormone (ADH, aslo referred to as vasopressin), the greatest fraction of the filtered plasma is reabsorbed in this segment of the nephron:
(6)   In the absence of the antidiuretic hormone (ADH, aslo referred to as vasopressin), the greatest fraction of the filtered plasma is reabsorbed in this segment of the nephron:
