Sure! The human respiratory system is a complex network of organs and tissues that enable the exchange of gases between the body and the environment. It includes the nose, throat, trachea, bronchi, and lungs. The primary function of the respiratory system is to provide oxygen to the body's cells and remove carbon dioxide, a waste product of cellular respiration. This process occurs through inhalation, where oxygen is taken in, and exhalation, where carbon dioxide is expelled.
