The human respiratory system is primarily responsible for the exchange of gases, particularly oxygen and carbon dioxide, between the body and the environment. It consists of several key organs, including the nose or mouth, trachea, bronchi, lungs, and diaphragm. Air enters through the nasal passages or mouth, is filtered and warmed, and then travels down the trachea into the bronchi, which branch into the lungs. Within the lungs, alveoli—tiny air sacs—facilitate the exchange of gases with the blood. The diaphragm, a muscle located below the lungs, plays a crucial role in breathing by contracting to allow air in and relaxing to push air out.

Answer 1

The human respiratory system helps us breathe and exchange gases like oxygen and carbon dioxide with the air around us. It includes a few important parts: the nose or mouth, trachea, bronchi, lungs, and diaphragm. When we breathe in, air comes in through our nose or mouth, gets cleaned and warmed, and then goes down a tube called the trachea. This tube splits into the bronchi, which lead to our lungs. Inside the lungs, there are tiny air sacs called alveoli that help swap oxygen and carbon dioxide with our blood. The diaphragm is a muscle right under the lungs that helps us breathe. It works like a pump: it contracts to pull air in and relaxes to push air out.
