  Side A   Side B
1
The urinary system does all of the following, except that it
a) eliminates...
 
d) excretes excess albumen molecules 
2
The primary function of the proximal convoluted tubule is
 
absorption of ions, organic molecules, vitamins, and water.
3
Typical renal blood flow is about ________ ml/min under resting conditions.
 
1200
4
The process of filtration occurs at
 
the glomerular (Bowman's) capsule.
5
Substances secreted by the distal convoluted tubule include
 
creatinine, penicillin, hydrogen and potassium ions, hydrogen and potassium...
6
Sympathetic stimulation of the kidney can do all of the following, except
a) increase...
 
increase the glomerular filtration rate
7
Under normal conditions, glomerular filtration depends on three main pressures:

1)...
 
1, 2, and 4 are correct
8
One mechanism the kidney uses to raise systemic blood pressure is to
 
increase secretion of renin by the juxtaglomerular complex.
9
The amount of filtrate produced by the kidneys each minute is called the ________.
 
GFR or glomerular filtration rate
10
The kidneys not only remove waste products from the blood, they also assist in the regulation...
 
blood pressure, blood ion levels, blood pH, and blood volume
11
The ions in highest concentration in the intracellular fluid are
 
proteins, potassium, and phosphate
12
Intracellular fluid (ICF) is found only within
 
the cells of the body
13
The principal ions in extracellular fluid are sodium, chloride, and ________.
 
bicarbonate
14
Which hormone plays a central role in determining the rate of sodium reabsorption and potassium...
 
aldosterone
15
The primary role of the carbonic-acid-bicarbonate buffer system is to
 
limit pH changes caused by organic and fixed acids.
16
When the pH of the extracellular fluid drops, the
 
kidneys secrete more hydrogen ions and fewer bicarbonate ions.
17
Which of the following descriptions best fits the acid-base disorder metabolic alkalosis?
 
consequence of prolonged vomiting
18
Blood leaves the glomerulus through a blood vessel called the
 
efferent arteriole.
19
Changes that occur in the urinary system with aging include all of the following, except
 
a) increased sensitivity to ADH.
20
Each of the following organ systems excretes wastes to some degree, except the...
 
e) endocrine
