What does the term "void" refer to in medical terminology?

In medical terminology, the term "void" specifically refers to the act of emptying the bladder. This process is essential for the expulsion of urine from the body, which is a normal part of kidney function and overall bodily waste management. The term is commonly used in clinical settings to discuss urinary patterns, assess bladder function, or address issues related to urination, such as urinary retention or incontinence.

Other options relate to different medical actions but do not capture the specific meaning of "void." For example, making a decision does not pertain to physiological processes, injecting a substance is typically described with terms like "administer" or "injection," and alleviating pain might be addressed with terms focused on pain relief or management. These terms signify distinctly different actions and do not align with the definition of "void" in the context of body functions.
