Urinary System Flashcards
Nephron
Renal corpuscle, proximal tubule, loop of Henle and distal tubule.
Uniferous Tubule
Nephron plus collecting tubule
Medullary Ray
Collecting duct and straight tubules at the center of a cortical renal lobule.
Interlobular Arteries
Branches of arcuate artery; at the lateral borders of a renal lobule.
Vasa Recta
Capillaries in the medulla that loop parallel to the loop of Henle
Renal Pyramid
Defines a lobe, contains collecting ducts, straight tubules and vasa recta
Cortical labryinth
Renal corpuscles plus convoluted tubules in cortex
JG apparatus
Macula densa, JG cells, and extraglomerular mesangial (lacis) cells
Podocytes
Visceral layer of Bowman’s capsule encasing glomerular capillaries
Renin
Enzyme secreted by JG cells; converts angiotensinogen to angiotensin I.
Renal Corpuscle
glomerulus plus Bowman’s capsule.
