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)

Answer 1

The human respiratory system is responsible for the exchange of gases between the body and the environment, primarily oxygen and carbon dioxide. It includes several key organs, such as the lungs, which facilitate gas exchange, the trachea, which conducts air to and from the lungs, and the diaphragm, which plays a crucial role in breathing by contracting and expanding the chest cavity. This system ensures that oxygen is delivered to the bloodstream while carbon dioxide is expelled from the body, supporting cellular respiration and maintaining pH balance. Overall, it plays a vital role in sustaining life by enabling efficient respiration and maintaining proper oxygen levels in the body.
