UPDATED ACTUAL Questions and
CORRECT Answers
What are the basic functions of the urinary system? - CORRECT ANSWER Filtration of blood to
remove metabolic waste, transportation of urine, and storage of urine.
What are the main organs of the urinary system? - CORRECT ANSWER Kidneys, ureters, urinary
bladder, and urethra.
Where are the kidneys located? - CORRECT ANSWER Lateral to T12-L3 vertebrae and protected
by the floating ribs.

What is the function of the renal capsule? - CORRECT ANSWER It is the transparent tissue
surrounding each kidney that provides protection.
What are the three support tissues of the kidneys? - CORRECT ANSWER Renal fascia, perirenal
fat capsule, and renal (fibrous) capsule.
, What is the renal cortex? - CORRECT ANSWER The superficial glandular layer of the kidney that
contains nephrons and blood vessels.
What structures are found in the renal medulla? - CORRECT ANSWER Renal pyramids, renal
columns, and collecting ducts.
What is the flow of urine through the kidney? - CORRECT ANSWER Minor calyx → major calyx
→ renal pelvis → ureter.
What is the function of the ureters? - CORRECT ANSWER They carry urine from the kidneys to
the urinary bladder.
Where does the urethra exit the urinary bladder? - CORRECT ANSWER Inferiorly.
How does the urinary bladder prevent backflow of urine? - CORRECT ANSWER When the

arteries and renal veins.
Why is the left renal vein longer than the right? - CORRECT ANSWER It often drains the left
adrenal and gonadal veins.
What are the minor and major calyces? - CORRECT ANSWER Minor calyces are cup-shaped areas
