What is micturition?

Micturition refers specifically to the act of urination, which is the process of discharging urine from the urinary bladder through the urethra to the outside of the body. This process is an essential bodily function that helps in removing waste and excess substances from the bloodstream.

Understanding the term is crucial in medical contexts, as it relates not just to urinary health but also to diagnosing potential issues like urinary tract infections or bladder dysfunction. The other options represent entirely different physiological processes: breathing pertains to the respiratory system, swallowing is part of the digestive process, and digestion itself involves breaking down food into nutrients, demonstrating the importance of being precise with medical terminology.
