Back 10

takes blood away from glomerulus (after filtration has occurred)

Front 11

Locate the PERITUBULAR CAPILLARIES

Back 11

low-pressure, porous capillaries adapted for absorption
• arise from efferent arterioles
• cling to adjacent renal tubules
• empty into renal venous system

Front 12

Locate the VASA RECTA

Back 12

long, straight efferent arterioles connected to peritubular capillaries (15% of nephrons) that flow Loops of Henle into medulla

Back 15

85% of all nephrons
• located in cortex of kidney
• short Loop of Henle
• efferent arteriole connects with peritubular capillaries

Front 16

Locate the JUXTAMEDULLARY NEPHRON

Back 16

15% of nephrons
• long loops of Henle extend deep into medulla
• peritubular capillaries (surround convoluted tubules) connect to vasa recta (long, straight capillaries parallel with loop of Henle)
