Introductory Quiz to the Urinary System

Urine moves down the ureters of the urinary system through the same process as food moves down the digestive tract. A process called peristalsis.

• True

• False

Which of the following terms refers to the urinary system?

• portal

• renal

• coronary

• cephalic

The renal system does not play a direct role in regulating which of the following?

• blood solute concentrations

• blood temperature

• blood pressure

• blood pH

Which of the following anatomical portions of a nephron connects the Bowman's capsule to the loop of Henle?

• distal convoluted tubule

• connecting tubule

• proximal convoluted tubule

• collecting duct

How many nephrons does the average adult kidney contain?

• exactly1

• roughly 100,000

• roughly 1,000,000

• roughly 1000

Urine is formed in a three-step process. Which of the following gives the correct order in which these steps take place in the nephron?

• tubular secretion, tubular reabsorption, glomerular filtration

• tubular reabsorption, tubular secretion, glomerular filtration

• glomerular filtration, tubular reabsorption, tubular secretion

• glomerular filtration, tubular secretion, tubular reabsorption

Which of the following is least likely to be present in the glomerular filtrate (the filtrate produced by the nephron before it enters the loop of Henle) of a healthy adult nephron?

• amino acids

• glucose

• electrolytes

• large protein molecules

The presence of which of the following in urine, even in small amounts, is indicative of a possible problem in the renal system of a patient?

• glucose

• creatinine

• urea

• sodium

As glomerular filtrate moves through the ascending loop of Henle, the filtrate becomes more dilute. Why?

• the ascending loop of Henle is permeable to water and ions

• the ascending loop of Henle is permeable to ions but impermeable to water

• the ascending loop of Henle is impermeable to water and ions

• the ascending loop of Henle is permeable to water but not to ions
