    Respiratory Health: Everything You Need to Know

    To better understand the most important facts about lung health, we must first define what a person’s lungs actually do. The lungs are a major part of the respiratory system, or the system responsible for breathing.

    Whenever a person breathes, the respiratory system takes in oxygen from the air, and expels carbon dioxide from the body. The lungs absorb the oxygen, and then distribute it through blood vessels to different parts of the body.

    All of the cells in our body require oxygen to function, so lungs are a very important organ. Lungs are crucial to our survival.

    This means that if there are any illnesses or diseases that affect our lungs, it would have dire effects on our overall health. And knowing the important facts about lung health can help you keep your lungs healthy and in tip-top shape.
