In 3-5 sentences, describe the human respiratory system and its functions.

The human respiratory system is a complex network of organs and tissues responsible for the intake of oxygen and the emission of carbon dioxide. It consists of the lungs, trachea, bronchi, and various smaller airways. The primary function of this system is to facilitate the exchange of gases between the body and the environment, allowing for the oxygenation of blood and the removal of waste gases. Additionally, it plays a crucial role in maintaining the acid-base balance in the body and helps regulate body temperature.

The human respiratory system is a complex network of organs that facilitate the exchange of gases between the body and the environment. It includes the nose, throat, windpipe (trachea), and lungs. The primary function of the respiratory system is to supply oxygen to the body's cells and remove carbon dioxide waste. This process occurs through inhalation, where oxygen is taken in, and exhalation, where carbon dioxide is expelled.
