The respiratory system is a vital biological mechanism responsible for facilitating the exchange of oxygen and carbon dioxide between the body and its environment. It involves multiple components, starting with inhalation through the nose or mouth. Air travels down the trachea into the lungs, where oxygen is transferred to the bloodstream and carbon dioxide is removed. This exchange occurs within tiny air sacs called alveoli. The circulatory system then transports oxygen-rich blood to tissues and organs, supporting energy production and various bodily functions. The respiratory system's efficient functioning is crucial for sustaining life and maintaining the body's equilibrium.
