what is the path of urine in kidneys
Give this one a try later!
1. pyramids
2. down collecting duct to papillae
3. minor calyx
4. major calyx
5. renal pelvis
6. ureter
7. bladder where urine is stored until ready to void
*draw flow chart of this
this part of renal tubule is where glucose, amino acids, water, electrolytes are
reabsorbed
-microvilli allow more reabsorption
,Give this one a try later!
PCT (proximal convoluted tubule)
A segment of the nephron that returns water from the filtrate to the bloodstream.
-where other nephrons can attach
Give this one a try later!
collecting duct
explain how the glomerural filtration rate works
Give this one a try later!
greater difference in diameter of afferent and efferent then the more
filtration happens
explain how the sympathetic regulation of filtration works
Give this one a try later!
afferent arteriole constricts to redirect blood to heart, brain, or kidneys
-aided by epinephrin
-constricts arterioles
-produces GFR
, when your blood pressure and osmolarity are low then this hormone is secreted. it
increases aquaporins which are channels that allow water to flow through
Give this one a try later!
ADH
this filters based on size of molecule
-negative charges are repelled because this is negatively charged
Give this one a try later!
basement membrane
describe osmotic gradient
Give this one a try later!
solvent sent out to high concentration= water follows = leaves descending
loop= concentration of urine
what are the four organs systems for excretion
Give this one a try later!
