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

Answer 1

The human respiratory system is responsible for the exchange of gases between the body and the environment. It enables the inhalation of oxygen through the nose or mouth, where it then travels down the trachea and into the lungs. In the lungs, oxygen is absorbed into the bloodstream while carbon dioxide, a waste product, is expelled from the body during exhalation. This process is crucial for maintaining cellular metabolism and overall homeostasis.
