Micturition refers specifically to the process of expelling urine from the bladder through the urethra. Therefore, among the provided options, the correct answer is:

A. passing out urine.

Here's a brief explanation of why this choice is correct:

Micturition is a physiological process that involves several steps, including the filling of the bladder, the signaling to the brain that it is time to urinate, and finally the voluntary contraction of bladder muscles to expel urine. When the bladder reaches a certain level of fullness, stretch receptors send signals to the brain, which then triggers the urge to urinate. This process is essential for the proper elimination of waste products from the body, particularly those dissolved in urine, such as urea and other excess substances. The other options refer to different bodily functions: removal of feces pertains to defecation, while the removal of uric acid and urea from blood relates to renal function and filtration processes in the kidneys, rather than directly involving micturition.
