In simple terms, the respiratory system comprises of organs, blood vessels, muscles and airways which are in control of the movement of oxygen and carbon dioxide. The key conditions that are covered in this area are asthma, chronic obstructive pulmonary disease (COPD), allergies and common issues such as coughs, colds, and respiratory infections.
During your studies you will find a slight overlap between infections and this section, so it is a good way to reinforce some of your learning (if you have previously thoroughly studied the infections section before tackling this part). Some of the respiratory system infections will include: bronchitis, acute exacerbation of COPD, pneumonia, sinusitis, and influenza.
There is a large variety of drug classes to focus on in this section which include some of the following: bronchodilators, corticosteroids, leukotriene receptor antagonists, mucolytics, antihistamines, antifibrotics, nasal decongestants, and antibacterials.
