6. The pressure in the glomerulus is _______ at 55mm Hg compared to 26mm Hg normally
High
Low
7. Parathyroid hormone acts primarily on the _________ and increases the reabsorbtion of Ca2+
Distal convolututed tubule
Proximal convoluted tubule
8. Autoregulatory mechanisms maintain a relatively constant GFR over ____________
Arterial pressure ranges
Tubular pressure ranges
9. _________ that get caught in the filtration membrane are engulfed by mesangial cells
Marcomolecules
Micromolecules
10. Aldosterone increases Na in the blood and __________ K
Reduces
Increases
11. Micturition means
Urination
Excretion
12. Atrial natriuretic peptide is contrasting to aldosterone therefore ________
Reduces blood volume and pressure
Increases blood volume and pressure
13. Glomerular capillaries have glomerular mesangial cells surrounding them and can contract to adjust the total surface area available for filtration
True
False
14. Antidiuretic hormone inserts aquaporins into the collecting duct, when overhydrated, ADH is decreased and therefore the collecting ducts are impermeable to water, thus _________
Less water reabsorbed
More water reabsorbed
15. The colloid osmotic pressure in glomerular capillaries is the pressure exerted by the proteins in the blood this ______ filtrate formation
Inhibits
Promotes
16. The foot processes make up the _________ layer, they have fenestrations that prevent any escaped macromolecules from passing further
Visceral layer
Peritoneal layer
17. Reabsorbed substances follow either the transcellular or ________ route
Paracellular
Bicellular
18. Glomerular filtration occurs when _______ forces fluids and solutes through a membrane
Hydrostatic pressuse
Chemotactic factors
19. _________ is the volume of filtrate formed each minute by the combined activity of all 2 million glomeruli of the kidney
The glomerular filtration rate
The hydrostatic pressure
20. Hydrostatic pressure must be tightly regulated in the kidney becuse if it rises, NEP rises and therefore ___________ rises
