What organ system includes the nose, trachea, and lungs?

The respiratory system encompasses the organs involved in the process of breathing and gas exchange, which is fundamental to respiration. This system includes the nose, which serves as the entry point for air; the trachea, a conduit that directs airflow to the lungs; and the lungs themselves, where the actual exchange of oxygen and carbon dioxide takes place.

Oxygen intake and carbon dioxide removal are vital for maintaining the body's metabolic processes. The respiratory system is responsible for ensuring that this exchange occurs efficiently, providing oxygen to the bloodstream and removing waste gases. This group of organs works in conjunction with other systems, such as the circulatory system, to facilitate the overall function of respiration and to support all bodily functions reliant on oxygen.
