How Much Do You Know About Kidney Health?
1. How much blood do your kidneys filter daily?
You didn't answer this question.
You answered
The correct answer is
One of the functions of your kidneys is to remove waste products and extra fluid from
the blood. Waste products come from your diet and normal breakdown of tissues. The
kidneys filter about 50 gallons of blood a day. Of that amount, about one-half to
two quarts of fluid and waste products are removed from the blood and passed out of
the body in urine.
2. Your kidneys are what part of which system in your body?

You answered
The correct answer is
The urinary system is made up of two kidneys; two ureters, which are thin tubes that
carry urine from the kidneys to the bladder; the bladder, which stores urine; two
sphincter muscles that prevent urine from leaking; nerves in the bladder; and the
urethra, which is the tube that carries urine outside the body. The kidneys not only
remove liquid waste from the blood, but also regulate electrolytes, or minerals; secrete
hormones that control blood pressure; stimulate red blood cell production; and help
maintain calcium balance.
3. What is the most common cause of kidney disease?
You didn't answer this question.
You answered
The correct answer is
High blood pressure (hypertension) and uncontrolled diabetes can damage the kidneys'
small blood vessels so they are unable to filter blood. This can eventually cause
kidney failure. Uncontrolled diabetes means high blood sugar over long periods of
time. Diabetes and high blood pressure are the leading causes of kidney disease. The
most common reason for a kidney transplant is the long-term effects of uncontrolled
diabetes.
4. How do most kidney-damaging diseases affect the kidneys?
You didn't answer this question.
You answered
The correct answer is
Each kidney contains about a million tiny filtering units called nephrons. A nephron
is made up of small tubes and blood vessels. Diseases that affect the kidneys can
damage the nephrons. As a result, the kidneys have problems getting rid of waste products.
5. Which of these races is the most likely to have high blood
pressure, which contributes to kidney failure?
You didn't answer this question.
You answered
The correct answer is
Black men ages
20 to 29 are 10 times more likely to develop kidney failure as a result of high
blood pressure than white men in the same age group. That risk increases 14 times
in
men ages 30 to 39.
6. Which of these over-the-counter medicines can damage the kidneys?
You didn't answer this question.

present no danger for most people when taken according to directions. But for people
with certain health conditions, these medicines may cause kidney problems. Also, if
you take these medicines regularly over a long period of time, you may increase your
risk for kidney problems. Talk with your healthcare provider about how to safely take
these medicines.

can damage the kidneys. Talk with your healthcare provider to be sure you’re getting
the proper nutrition, as well as making the appropriate changes in your diet to help
your kidneys work well.
