Immunity 101 – An optimal respiratory system to cope with external aggressions 🍀

As the entry point of the oxygen we breathe in, the same way the gut is exposed to external pathogens we may ingest, the lungs are exposed to viruses and bacteria that could be in the air. The lining of the lungs, formed of epithelial cells, secretes mucus that catches foreign substances. Small hairs (called cilia) would then push it up to be expelled through a cough. The same lining is also made of macrophages white cells, which are able to destroy foreign substances that enter the lungs. 

So when our lungs are weak, we are not equipped with a performant defence mechanism. This is one other reason for the importance of maintaining an optimal respiratory system. Once the lungs are weakened, they cannot fulfil their function and defences are not optimal, creating an entry point for harmful pathogens such as bacteria and viruses. This is more particularly true during specific seasons or times of the year, such as the influenza period, common cold and more humid season.

Having strong lungs and supporting them during periods we are more at risk would help strengthen our defences and help our lungs recover faster, in the unfortunate case of infection, to avoid potential complications such as bronchitis, sinus infection or even pneumonia.
