总结
The human respiratory system facilitates gas exchange, providing oxygen for cellular respiration and removing carbon dioxide. Air travels through the nasal cavity, pharynx, larynx, and trachea into the lungs, where bronchi and alveoli enable gas diffusion. The system works with the circulatory system and is regulated by the nervous system to maintain homeostasis.
