Flashcards in Urinary System Deck (44)
What is the function of the urinary system?
pH, fluid, electrolyte regulation
Liquid waste elimination
What is the functional unit of the kidney?
What connects the kidneys to the urinary bladder?
What stores urine?
When leaving the bladder, what does urine go through?
The ion balance and excretion is accomplished by a _______________ mechanism in the nephron.
Blood is filtered at the __________ ________ such that particles smaller than ______ molecular weight pass into tubule system, most of which will be selectively reabsorbed in the convoluted tubules.
The distal wall of Henle's loop (ascending limb) then actively transports ____ ions (Na+ follows passively) out of the tube and into the surrounding _________ (peritubular) fluid.
The relatively high _____ concentration draws water out of the tube (esp collecting ducts), thereby ______ the concentration of urine left behind.
The salt ions are then transported back into the descending limb of the loop, thus _______ the urine dehydrating/concentrating power of the loop.
The countercurrent term identifies that descending limb fluid is flowing in a direction _______ that in the ascending limb, which allows for the recycling of _______.
Countercurrent multiplier mechanism allows for urine to be concentrated up to ______ times normal plasma levels
Blood goes out to the ______ and then down into the ______ to be filtered
Kidneys produce what 2 chemicals?
Erythropoieten and renin
What effect does aldosterone have on the kidneys?
How does blood get into glomerular capsule?
Capillary have holes in them that "bleed" - comes in at a high blood pressure
Only the _______ actually makes it through glomerular capsule
Plasma (at 300 mOsm)
The farther down the descending limb, the ______ the concentration.
The ascending limb is ____________ (water cannot leave/enter)
ADH causes ________ loss in distal convoluted tubule
Alcohol stops what from working, causing water to remain in the distal convoluted tube?
What are the glands above the kidneys called?
Inferior vena cava
Name #9 and #10
Iliac artery and vein
Name #11 and #13
Right renal vein and artery
Name #12 and #14
Left renal vein and artery
Psoas major muscle
Fibrous outside capsule
