urinary system's primary function
|
cleanse the blood of waste products
|
|
|
parts of the urinary system
|
two kidneys
two ureters one urinary bladder one urethra |
|
|
erythropoietin
|
hormone necessary for red blood cell production
produced by the kidneys |
|
|
processes by which the kidneys help maintain homeostasis
|
1. blood filtration, reabsorption and secretion
2. fluid balance regulation 3. acid-base balance regulation 4. hormone production |
|
|
hilus
|
medial side of the kidney
where blood and lymph vessels, nerves, and ureters enter and leave the kidney |
|
|
renal pelvis
|
urine collection chamber that forms the beginning of ureter
lined with transitional epithelium |
|
|
renal cortex
|
outer portion of the kidney
reddish-brown, rough granular appearance |
|
|
renal medulla
|
inner portion around the renal pelvis
smooth appearance, darkpurple |
|
|
nephron
|
basic functional unit f the kidney
|
|
|
renal corpuscle
|
located in the cortex of the kidney
made up of glomerulus and Bowman's capsule |
|
|
glomerular filtrate
|
fluid that is filtered out of the blood
|
|
|
proximal convoluted tubule (PCT)
|
continuation of bowman's capsule, longest part of nephron
cuboidal with a brush border |
|
|
function of PCT
|
reabsorption and secretion
|
|
|
loop of Henle
|
continues from PCT
brush border |
|
|
distal convoluted tubule (DCT)
|
continuation of ascending loop of Henle
|
|
|
juxtaglomerular apparatus
|
neural regulatory system for the kidney
maintains nerve stimulation and shuts of blood supply to certain glomerulo dereasing urine production |
|
|
renin-angiotensin-aldosterone mechanism
|
renin is released from renal cortex activating enzymes to produce angiotensin which causes vasoconstriction and production of aldosterone which increases sodium return to the bloodstream
