Quizplus · Accepted Answer

Expectorants are drugs that work primarily to remove secretions from the respiratory tract by making the secretions thinner, thereby making it easier for the patient to cough them up. Anticholinergics work by relaxing the smooth muscles in the bronchial tubes, thereby increasing airflow in the lungs. Oxygen is used to improve oxygen delivery to the body's tissues. Antitussives work to suppress coughing.
