Urinary System: Unit Review and Quiz
|
Unit Review
Here is what we have learned from this unit:
- The urinary system rids the body of waste materials, regulates
fluid volume, maintains electrolyte concentrations in body
fluids, controls blood pH, secretes erythropoietin, and
renin.
- The components of the urinary system are the kidneys,
ureters, urinary bladder, and urethra.
- The primary organs of the urinary system are the kidneys,
which are located retroperitoneally between the levels of
the twelfth thoracic and third lumbar vertebrae.
- The cortex and medulla make up the parenchyma of the kidney.
- The central region of the kidney is the renal pelvis,
which collects the urine as it is produced.
- The functional unit of the kidney is a nephron, which
consists of a renal corpuscle and a renal tubule.
- The ureters transport urine from the kidney to the urinary
bladder.
- The urinary bladder is a temporary storage reservoir for
urine.
- The urethra is the final passageway for the flow of urine.
- The flow of urine through the urethra is controlled by
an involuntary internal urethral sphincter and voluntary
external urethral sphincter.
Quiz
To test how much you have learned from this unit, two types
of quizzes have been created. The first type is a true-false
quiz. The quiz questions are grouped into several sets of
two questions each to reduce the size of the content on each
page. When you finish the questions in one set, click the
Next button ( a right-pointing arrow icon located in the Title
Bar) to proceed to the next page.
The second type is a drag-and-drop quiz, in which, by using
the mouse pointer, you drag a textual or graphic element to
a target area to show your knowledge of the material covered
in the unit. Note that the object you are dragging will snap
back to its original position until it is placed in the correct
target area. Try to drag the object as close to the center
of the target area as possible so that the object will snap
to the target area when you chose a correct answer.
