Physiology Ch 26 & Ch 27

The urinary system does all of the following, except that it
a) eliminates organic waste products.
b) contributes to stabilizing blood pH.
c) regulates blood volume.
d) excretes excess albumen molecules.
e) regulates plasma concentrations of electrolytes.

The primary function of the proximal convoluted tubule is

Typical renal blood flow is about ________ ml/min under resting conditions.

The process of filtration occurs at

Substances secreted by the distal convoluted tubule include

Sympathetic stimulation of the kidney can do all of the following, except
a) increase the glomerular filtration rate.
b) trigger renin release.
c) produce renal ischemia.
d) produce powerful vasoconstriction of the afferent arterioles.
e) increase the glomerular filtration rate and trigger renin release.

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

One mechanism the kidney uses to raise systemic blood pressure is to

The amount of filtrate produced by the kidneys each minute is called the ________.

The kidneys not only remove waste products from the blood, they also assist in the regulation of

The ions in highest concentration in the intracellular fluid are

Intracellular fluid (ICF) is found only within

The principal ions in extracellular fluid are sodium, chloride, and ________.

Which hormone plays a central role in determining the rate of sodium reabsorption and potassium secretion?

The primary role of the carbonic-acid-bicarbonate buffer system is to
