Urinary system organs:- 2 kidneys (T12-L3)- 2 ureters, connect kidneys to bladder- urinary bladder- urethra
Kidneys:- control blood composition
filter blood 60 times/day180 L (45 gal) of filtrate formed daily
1.5 L eliminated as urine- help regulate BP by secreting renin- gluconeogenesis- erythropoiesis
Protective coverings of kidneys (deep to superficial):- renal capsule- adipose capsule- renal fascia
Nephrons = functional unit of kidneys
Tubules
1. Cortical Nephron
2. Juxtamedullary Nephron
Renal corpuscle = glomerular capsule and glomerulus (blood capillary), filtration siteGlomerular capsule
a. parietal layer - outer coveringb. capsular space - separates parietal and visceralc. visceral layer - Podocytes
Endothelial capsular membrane (filtering membrane) = visceral layer of capsule + endothelium of glomerulus.
