1

organs located on posterior abdominal wall around T12-L3 lateral to vertebrae

kidneys

renal capsule

15

sinus

17

The ___ is an epithelial tube within the kidney that carries the filtrate from the blood

18

The pathway of blood from the renal artery to the collecting duct is:

renal artery --> afferent arteriole --> glomerular capillaries in Bowman's capsule --> proximal convoluted tubule --> loop of Henle --> distal convoluted tubule --> collecting ducts

renal papilla

27

The ____ is where the papillary ducts drain into the minor calyx

renal papilla
