The human respiratory system is primarily responsible for the exchange of oxygen and carbon dioxide between the body and the environment. Key organs in this system include the lungs, where gas exchange occurs, the trachea, which air travels through to reach the lungs, and the diaphragm, a muscle that aids in breathing by contracting and relaxing to facilitate airflow. This system ensures that oxygen reaches the bloodstream to support cellular functions while removing carbon dioxide, a waste product of metabolism. Overall, it plays a vital role in maintaining the body's homeostasis and overall health.
In 3–5 sentences, explain the function of the human respiratory system. Include the names of at least three organs in your answer.(4 points)
