Explanation:

"Sputum" is an expectoration because it is being expelled from the mouth by spitting. In medical setting, it is being submitted to the laboratory in order to aid in the diagnosis of disease–oftentimes, it is respiratory in nature. This is also the term used when the mucus is being coughed out. Most people who have symptoms of coughing are advised by the physician to submit a sputum sample to the laboratory.
