Lab 28: Urinary Syst

QuestionAnswer
Cortex outer region of kidney
Cortex contain nephrons
Medulla inner region of kidney
Kidney highly vascular
Medulla & Cortex urine production
Medullary Pyramid Urine transport to papilla
Renal Pelvis Funnels urine into ureter from the calyces
Renal vein carry filtered blood away
Renal artery carry blood to be filtered
Ureters transport urine from the kidneys to the bladder
Major calyces drain urine into the renal pelvis from minor calyces
Minor calyces drain urine into major calyces from papillae
Segmental artery Branch from renal artery to interlobar artery
Cortical radiate arteries/veins Branch from acuate to afferent
Interlobar arteries/veins Branch from segmented to acuate
Renal Corpuscle surrounded by Bowman's corpuscle
Renal Corpuscle site of filtration, produces filtrate
Bowman’s capsule surrounds glomerulus, collects filtrate
Glomerulus capillary network, filters blood under pressure
Afferent arteriole brings blood to glomerulus, larger diameter increases pressure
Efferent arteriole drains blood from glomerulus, smaller diameter maintains pressure
Proximal convoluted tubule (PCT) major site of reabsorption, reabsorbs water, glucose and ions, contains microvilli
Distal convoluted tube (DCT) Reabsorb & secrete water & ions; Influenced by hormones (Aldosterone - Na+ reabsorption & PTH - Ca++ reabsorption)
Loop of Henle descending limb; permeable to water; water leaves filtrate
Descending Limb Water reabsorption only
Ascending Limb Ion reabsorption only; Impermeable to water
Collecting duct Reabsorb water by hormone; Regulated by ADH
