Expectorate refers specifically to the process of expelling phlegm, mucus, or other substances from the respiratory tract through spitting or coughing. This term is often used in medical contexts, particularly when discussing conditions related to respiratory health, where the act of clearing out such substances from the throat or lungs is necessary for better breathing or health management.

Understanding the meaning of expectorate is crucial in fields such as medicine and nursing, as it can indicate underlying health issues, necessity for effective communication about symptoms, and proper patient care practices. The other options presented do not align with this definition; they describe entirely different actions.
