The integumentary system is the largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain. (Physiopedia, n.d)
This histology image of a mammal’s trachea shows how well the airway is protected and maintained. You can see the pseudostratified epithelium with cilia and goblet cells, which help trap and move dust or mucus out of the airway. The cilia act like little brushes that sweep particles away, while goblet cells produce mucus for protection. It’s amazing how the body has this natural cleaning system to keep our breathing passages clear and healthy.
