The pleural membrane is the innermost layer of the respiratory system that allows air to enter and exit the lungs through their small airways. It is composed of specialized cells called muscarine neurons, which are tightly packed with muscle fibers that contract when the flow of air through them increases.

During inspiration, the pleural membrane contracts as oxygen enters the body and releases carbon dioxide out into the atmosphere. This exchange of gases is what causes the body’s natural “bleed” and helps to prevent fluids from building up in the airways and causing them to collapse.
In contrast, during expiration, the pleural membrane relaxes, allowing carbon dioxide to pass out into the bloodstream. This process helps to prevent the formation of blood clots and reduce the risk of heart failure.
However, despite its importance for maintaining the health of the lungs, there can be instances where the pleural membrane may fold and become misconfigured, leading to a decrease in the amount of gas that can be entered and exhaled by the body. This condition, known as parotiditis, occurs when the structure of the pleural membrane becomes damaged or abnormal, leading to problems with airflow and gas exchange.
Parotiditis can affect anyone who, but it is particularly common in individuals with certain medical conditions, such as sarcoidosis or emphysema. In these cases, the symptoms may include difficulty breathing, fatigue, weight loss, and shortness of breath.
In order to prevent parotiditis, it is important to maintain good hygiene, follow recommended respiratory practices, and contact healthcare professionals if you experience any signs of chronic left-sided parotiditis. Treatment often involves medications and physical therapy to help manage symptoms and improve airway function.

Overall, the pleural membrane and surfactant play a crucial role in maintaining the health of the lungs. While there can be times when this delicate balance may need to be adjusted, proper care and management can help to prevent complications and promote overall health.
