Our body is a machinery and all the organs are interconnected to one another in some way or the other. We breathe in and breathe out to keep our body living and healthy but never for once do we think how hard the lungs work to keep up with the respiratory function. We take our body for granted most times and we realize its importance only when it starts breaking down. Since breathing is a part and parcel of our living, we seldom take care of our lungs intentionally and realize its importance only when we face some respiratory issues. When our lungs are not functioning properly we also face some serious heart problems.
