The respiratory system plays a vital role in gas exchange, facilitating the intake of oxygen and the expulsion of carbon dioxide. The main organs include the nose, pharynx, larynx, trachea, bronchi, lungs, and alveoli, each contributing to the process of breathing and gas exchange. Understanding this system is crucial for recognizing respiratory disorders and the importance of respiration in maintaining homeostasis within the body.
