The correct option is B micturition
∙ Micturition is the process of excreting urine out of the body.
∙ Urine is produced by the kidney and transported to the urinary bladder by a pair of ureters.
∙ Urinary bladder can store 300-800 mL of urine.
∙ After the bladder is filled, a pressure is exerted on to the walls of the urinary bladder.
∙ This causes its release from the bladder through urethra.
