chapter 26 Flashcards
urinary system and homeostasis
alters blood comp. , pH, volume, and pressure, maintaining blood osmolarity, excretes wastes and foreign substances, produces hormones
how many tissue layers surround the kidney and what are they
3 (superficial to deep_)
renal fascia
adispose capsule
renal capsule
what are the 8 kidney functions
regulation of blood ionic composition, reg. of blood pH, reg. of blood Vol., reg of BP, maintenance of blood osmolarity, prod. of hormones, reg. of blood glucose levels, excretion of wastes
what are the two distinct regions of the parenchyma
renal cortex and renal pyramids
what is the urine flow
papillary duct to minor major calyces to renal pelvis to ureter to urinary bladder
kidneys are how much of your body weight
.5 %
about 25% cardiac output at rest
how much renal blood flow is there per min
1200 ml
each nephron contains what
- afferent arteriole
- glomerular caps.
- efferent arteriole
- peritubular cap (cortex)
- vasa recta (medulla)
nephron =
functional unit of kidney
how many nephrons per kidney
approx 1 mill
what are the two general sections of nephrons
renal corpuscle (plasma) renal tubule filtration
renal corpusule contains
glomerulus
bowmans capsule
renal tubule contains
proximal convoluted tubule loop of hence dital convoluted tubule collecting duct papillary duct
