Urinary Exam 1

• 1. filter blood (urea)
• 2. regulate blood volume (ECG)
• 3. Epo production
• 4. vit D/Ca 2+ homoostasis

right

• glomerulus (Bowman's capsule)
• proximal convoluted tuble-PCT
• diatal convoluted tuble-DCT
• cortical collecting duct
• juxtoglomerular apperatus

• loops of Henle
• medullary collecting ducts
• papillary ducts

glomerulus--> PCT--> LH--> DCT--> collecting duct

• o2 & nutrients to nephron
• substances for secretion
• returns reabsorbed h2o & solutes

• glomerulus located in outer to mid region of cortex
• LH shorter
• efferent arteriol branches into peritubular capillaries
• capillary network carries O2 & nutrients to nephorn--> serves as pathway for return of reabsorbed H2O & solutes

• glomerulus larger & in cortex next to medulla
• LH longer (deeper into medulla)
• efferent arteriol forms peritubular capillaries & vasa recta (conc. and dillutes urine)

renal artery--> interlobar artery--> arcuate artery--> interlobular artery--> afferent arteriole--> glomerular capillaries--> efferent arteriole

interlobular vein--> arcuate vein--> interlobar vein--> renal vein
