Urinary System Flashcards
The functional unit of the kidney is called a glomerulus (true or false)
False (it’s a nephron)
A glomerulus is fed by an afferent arteriole (true or false)
True
A glomerulus is drained by an afferent arteriole (true or false)
False (efferent)
The peritubular capillary vasa recta branches off an efferent arteriole (true or false)
True
Average blood hydrostatic pressure (BHP) is 55 mmHg (true or false)
True
Average capsular pressure (CP) is 30 mmHg (true or false)
False (15 mmHg)
Average colloid osmotic pressure (COP) is 15 mmHg (true or false)
False (25 mmHg)
Net filtration pressure is +10 mmHg
True
GFR is the glomerular filtration rate of one kidney (true or false)
False (both kidneys)
If Kf is 24 ml/min and NFP is NORMAL then GFR = 125 ml/min (true or false)

True
Normal BUN level is 6-18 mg/dl (true or false)
True
Uremia results in severe Azotemia (true or false)
True
About 85% of nephrons are juxtamedullary nephrons (true or false)
False (cortical not juxtamedullary)
The vasa recta surrounds the Loop of Henle in the renal medulla (true or false)
True
Intercalated cells are cuboidal cells with microvilli (true or false)
True
Cuboidal cells in the connecting tubules and ducts lack microvilli (true or false)
False (they have short and sparse microvilli)
Principal cells help maintain water and salt balance (true or false)
True
Intercalated cells help maintain acid-base balance (true or false)
True
The glomerulus is composed of fenestrated capillaries (true or false)
True
