Orinar

Orinar is a Spanish verb that means to urinate, i.e., to discharge urine from the body through the urethra. The related noun la orina refers to urine. In both medical and everyday language, orinar describes the act of micturition. The term comes from Latin urina, with the Spanish infinitive suffix -ar.

Physiology and context: Urination is part of the urinary system, involving the kidneys that form urine, the bladder that stores it, and the urethra that conducts it out of the body. The process is controlled by sensory nerves and the nervous system, and typically occurs when the bladder is sufficiently full, though voluntary control allows postponement. Normal frequency varies with age, fluid intake, and health, but most adults urinate several times a day and sometimes at night.

Usage and related terms: Orinar can be used in formal and informal contexts. Informal expressions in Spanish include hacer pipí. Medical terms related to urination include dysuria (painful urination), nocturia (urination at night), polyuria (excessive urination), and urinary incontinence. Abnormal symptoms such as blood in the urine (hematuria), persistent dysuria, or significant changes in urination patterns warrant medical evaluation.
