in 3-5 sentences, explain the function of the human respiratory system. include the names of at least 3 organs in your answer.

Answer 1

The human respiratory system is responsible for the exchange of gases between the body and the atmosphere, primarily oxygen and carbon dioxide. Key organs involved in this process include the lungs, where gas exchange occurs in the alveoli, the trachea, which serves as the airway connecting the throat to the lungs, and the diaphragm, a muscle that facilitates breathing by contracting and relaxing to control airflow. This system ensures that oxygen is supplied to the bloodstream while removing carbon dioxide, a waste product of cellular metabolism.
