Urinary system Flashcards
Hilus of kidney
indented area where vessels goes in
layer of kidney
cortex, medulla and pelvis
cortex of kidney
tough protective capsule, dark red
Medulla of kidney
central area, paler than cortex
pelvis
inner section witish color
nephron
filters blood and forms urine
ultrafiltration
glomerulus and capsule, high pressure forces fluid small molecules into capsule (osmotic water back to blood)
proximal convoluted tube
reabsorption into the body of: water sodium ions chloride ions amino acids proteins urea vitamins glucose
distal convoluted tube
reabsorption back into the body of:
water
chloride ions
amino acids
Descending loop of Henle
water is absorbd by the body, primitive urine is highly concentrated
Ascending loop of henle
body reabsorbs Na, less concentrated
collecting duct
ADH secures homoestasis of water
RAAS
renin: low arterial pressure
Angiotensinogen: inactive
angiotensin: vasoconstriction and realease of aldosterone
aldosterone: regulates absorption of na in dct
Baroreceptors
walls of blood vessels, monitor blood pressure
osmoreceptors
hypthalamus, monitor osmotic pressure of plasma
