What is the human respiratory responsible for?

The human respiratory system is responsible for the exchange of gases between the body and the environment, primarily facilitating the intake of oxygen and the expulsion of carbon dioxide. It includes structures such as the lungs, trachea, and alveoli, which work together to ensure efficient gas exchange during the process of breathing. Additionally, the respiratory system plays a role in regulating blood pH and protecting the body from inhaled pathogens and irritants. Overall, it is essential for maintaining cellular respiration and overall metabolic function.
