Question

Identify a process based on the following clues.
$\bullet$ It is regulated by the nerves and muscles of the urine storage organ.
$\bullet$ A pair of sphincters play a vital role in regulating this process.

• A. Micturition
• B. Reabsorption
• C. Filteration
• D. Secretion

Answer 1

The correct option is A Micturition

$\bullet$ Micturation is the process of excreting urine out of the body.
$\bullet$ Urine is produced by the kidney and transported to the urinary bladder by a pair of ureters.
$\bullet$ Urinary bladder can store 300-800 mL of urine.
$\bullet$ After the bladder is filled, a pressure is exerted on the walls of urinary bladder. This triggers off an automatic reflex action causing relaxation of a sphincter called upper sphincter.
$\bullet$ Another sphincter called lower sphincter is regulated by the brain.
$\bullet$ When both the sphincters are open micturation happens, resulting in the removal of urine out of the body.
