renal corpuscle
|
bowman's capsule + glomerulus
|
|
|
bowman's capsule
|
cup-shaped structure around glomerulus.
-visceral: surrounds capillary tuft; consists of podocytes that sort what particles go through. -parietal: outer epithelium |
|
|
capsular space
|
where substances that leak through visceral layer sit waiting to pass into proximal tubule
|
|
|
proximal conv. tubule
|
-most reabsorption of H2O
-Active reabsorption of small molecules to surrounding peritublar capillaries -secretion of highly charged particles |
|
|
descending henle's loop
|
reabsorption of H2O, Na and Cl
|
|
|
Ascending Henle's loop
|
reabsorption of Na Cl
|
|
|
Distal conv. tubule
|
secretion: H2, NH4+, urea; excrete Nitrogen.
Control of blood pressure w/ special cells. |
|
|
Collecting tubule, duct, papillary duct
|
urine enters from many nephrons; released into minor calyx.
Last point of concentration = ADH |
|
|
Ureters
|
transport urine via peristaltic contractions to bladder. Enters at oblique angle to prevent backwash out of bladder into tubule
|
|
|
ureterovesicular junction
|
where painful kidney stones often occur.
|
|
|
bladdar/detrusor
|
storage of urine; muscular wall is detrusor, autonomic
|
|
|
Sympathetic/Parasympathetic Response to bladder/urinary system
|

Parasympathetic: loosen the sphincters; let it go. you're resting/reposing |
