Expectoration

Expectoration is the act of coughing up and spitting out material from the lungs and airways, typically containing mucus, phlegm, or other substances. It is a natural bodily function designed to clear the respiratory tract of irritants, foreign matter, or secretions. The nature of the expectorated material can provide valuable diagnostic information about a person's respiratory health. The process often involves a forceful expulsion facilitated by a deep inhalation followed by a contraction of the abdominal and intercostal muscles. While expectoration is a normal physiological response, excessive or unusual expectoration may indicate an underlying medical condition.

Expectoration meaning with examples

• The doctor examined the patient's expectoration, noting its color and consistency to diagnose a possible lung infection. The patient coughed repeatedly, producing thick, yellowish phlegm, suggesting a bacterial bronchitis. Further tests were ordered based on the characteristics of the expectorated material to determine the specific pathogen and the most effective treatment course. The lab results were then used to find the best medications to cure her bronchitis.
• After enduring a week of constant coughing, the hiker finally experienced the unpleasant sensation of expectoration. The material was clear and thin, a sign his cold had gotten better.

It was the worker's responsibility to have regular tests to ensure his lungs were safe.
• During the tuberculosis outbreak, health officials closely monitored instances of expectoration among the population. They sought to determine the spread of the contagious disease. Public health protocols included requiring individuals with a cough to cover their mouth and nose to reduce aerosol spread. Regular and consistent tracking of expectoration was important to identify new cases and prevent the spread of the disease.
