In response to increased levels of aldosterone, the kidneys produce
urine with a lower concentration of sodium ions.
Under normal conditions, glomerular filtration depends on three main pressures:
1) blood hydrostatic pressure
2) capsular hydrostatic pressure
3) capsular colloid osmotic pressure
4) blood colloid osmotic pressure
5) urinary bladder hydrostatic pressure
1, 2, and 4 are correct.
Each of the following organ systems excretes wastes to some degree, except the ________ system.
The following is a list of the blood vessels that carry blood to the kidney.
1. afferent arteriole
2. arcuate artery
3. interlobar artery
4. renal artery
6. cortical radiate artery
7. efferent arteriole
8. peritubular capillary
The proper order in which blood passes through these vessels is
4, 3, 2, 6, 1, 5, 7, 8.
The primary function of the proximal convoluted tubule is
absorption of ions, organic molecules, vitamins, and water.
A patient excretes a large volume of very dilute urine on a continuing basis. This is may be due to
absence of ADH.
Which of the following formulas will allow you to calculate correctly the net filtration pressure (FP)? (Hint: CsHP is capsular hydrostatic pressure.)
FP = BHP - (CsHP + BCOP)
Changes that occur in the urinary system with aging include all of the following, except
increased sensitivity to ADH.
________ is an inflammatory disorder of the glomeruli that affects the filtration mechanism of the kidneys.
