lung
The lung is the unsung guesthouse for air within the body, quietly performing its duties unseen until it screams in protest when afflicted. It resides silently in the chest cavity, repeating the daily miracle called respiration, only to betray us the moment disease intrudes. Humans can neither monopolize its moods nor consistently express gratitude for its efforts until the last resort, yet they gladly poison it with tobacco smoke and exhaust gases. A melancholy conspirator in dark irony, the lung clings to hope in every deep breath taken.
