Term
the glomerulus differ from other capillary beds in the body in that it _________.
Definition
is drained by an efferent arteriole
Term
the descending limb of henle
Definition
contains filtratesthat becomes more concentrated as more water is pulled out by osmosis
Term
the filtration mebrane includes
Definition
glomerular endothelium
podocytes
basement membrane

the fluid in Bowmans capsule is similar to plasma except that is does not contain a significant amount of ___________.
Definition
plasma proteins
Term
Alchohol is a diuretic because it __________
Definition
inhibits the release of ADH
Term
the functoion of angiotensin because it ______________.
Definition
stimulates ADH secretion
constricts arterioles
blood pressure up
stimualtes aldosterone increaes sodium retention
Term
the primary factor that favors filtrate formation at the glomerlus is the ____________________.
Definition
glomerular hydrotatic pressure
Term
NOt a method by which the cells of the renal tubules can raise blood pH
Definition
secreting sodium ions
Term
physiological factors of thirst
Definition
rise in plasma osmolaity
Term
cause of respiratory acidosis
Definition
holding breath

when the cells of the macula densa sense a low Na+ level in the filtrate tthey signal the afferent arteriole to.....
Definition
dialate
Term
rennin is released when
Definition
the arteriole blood pressure is low
Term
cells of the proximal convuluted tubule can be distinguished from cells of the distal convuluted tubules because...
Definition
the cuboidal cells of the PCT have many microvilli and the DCT cells have few
Term
what is NOT part of the juxtaglomerural aparatus
Definition
the cells of the collecting duct
Term
Why does the body always have urea to excrete?

The ureter transprts urine from the kidney to the urinary bladder.
Definition
Term
glomerular filtration is NOT an ATP driven process
Definition
Term
the collecting duct is NOT impermeable to water in the preence of ADH
Definition
Term
angiotensin II is a substance made by the body to increase blood pressure
Definition
Term
aldosterone is a hormone that cases the renal tubules to reclai sodium ions from the filtrate
Definition
Term
urea is reabsorbed in the ascening loop of henle
Definition
Term
atrial naturetic peptide inhibits sodium reabsorption
Definition
Term
the macula densa cells are chemoreceptors that respond to changes in the NaCl content of the filtrate
Definition
Term
Electrolytes have greater osmotic power than nonrecpertors because they dissciate in solution
Definition
Term
thirst system is located in the
Definition
hypotyhalmus
Term
premensrtual edema may be due to enhanced reabsorption of sodium chloride
Definition
Term
