Kidney Flashcards
Anatomical organization of the Kidney
- Capsule
- Renal Cortex
- Renal Medulla
- Renal Pelvis
The renal cortex is composed of
- Bowman’s Capsule
- Proximal and distal Convoluted tubules
The renal medulla is composed of
Renal pyramids
The renal pelvis is composed of
Major and minor Calyces
How many nephrons per kidney
800,000-1,000,000
The amount of nephrons decreases by ___ % every year after the age of 40
10%
Each large collecting duct (=250/kidney) receives urine form ______ nephrons
4000
Cortical nephrons have glomeruli located in ______ and have short ____-
Outer cortex, short loops of Henle
Juxtamedullary nephrons (20-30% of total) have glomeruli ______ and have long ______
deep in renal cortex near medulla, long loops of Henle
_______ have long efferent arterioles associated with peritubular capillaries (vasa recta)
Juxtaglomerular nephrons
Juxtaglomerular nephrons have long efferent arterioles associated with
peritubular capillaries (vasa recta)
Kidney’s receive about ____ % of total cardiac output
22 % (1100mL/min)
Efferent arterioles help regulate
hydrostatic pressure in both sets of capillaries (glomerular and peritubular (vasa recta)
High hydrostatic pressure in glomerular capillaries is
about 60 mm Hg
What does high hydrostatic pressure in glomerular capillaries (about 60 mm Hg) cause
rapid fluid filtration
