Lab - Urinary Functions

renal fascia

anchors kidneys in place

adipose capsule

protects against trauma

renal capsule

protects kidneys against infection from other structures

hilum

entry/exit site for ureter, renal arteries/veins, lymphatics, and nerves

cortex

houses cortical nephrons

renal columns

pathway for blood flow to and from cortex

medulla

houses pyramids

pyramids

contain collecting ducts

papillae

site where urine exits the pyramid

collecting ducts

collect urine from nephrons

minor calyx

collects urine from papilla

major calyx

collects urine from minor calyces

renal pelvis

collects urine from major calyces

renal artery

delivers oygenated blood to kidneys

renal vein

drains deoxygenated blood away from kidneys

afferent arteriole

controls blood flow into glomerulus

glomerulus

filtration of blood

efferent arteriole

controls blood flow out of glomerulus

bowmans capsule

filtration of blood

proximal convoluted tubule

reabsorption and secretion

loop of Henle

limited reasborption

distal convoluted tubule

secretion and hormone-controlled reabsorption

peritubular capillaries

reabsorption and secretion
