- a Which is not correct regarding the innervation of the kidney?
Parasympathetic innervation is from the vagus nerve.
The kidney is served by the renal plexus.
Sympathetic innervation is from segments T10-T12 of the spinal cord.
Sympathetic stimulation causes vasoconstriction of the renal blood vessels.
Parasympathetic stimulation decreases the rate of filtrate formation.
- b The countercurrent multiplier is a system by which the:
nephron loop multiplies the concentration of salts in the interstitial fluid of the kidney medulla.
nephron loop dilutes the concentration of solutes in the tubular fluid at its hairpin turn.
vasa recta secretes multiple amounts of metabolic wastes against their concentration gradient.
vasa recta becomes more concentrated with nitrogenous wastes than the urine.

5 True/False questions
b → Parathyroid hormone (PTH):

inhibits reabsorption of both calcium and phosphate.
e → In the process of urine formation, first:
filtrate is formed, then tubular fluid, then urine.
tubular fluid is formed, then filtrate, then urine.
b → In response to low blood ________, the kidneys secrete __________.
a → The kidneys are located ___________ the peritoneum.
b → The capillaries of the glomerulus differ from most other capillary networks in the body because they:

drain into an arteriole instead of a venule.
contain no endothelium.
absorb nutrients from the glomerular capsule.
