How lungs Work
Your lungs are part of a group of organs and tissues that all work together to help you breathe. This system is called the respiratory system. The main job of the respiratory system is to move fresh air into and get waste gases out of the body. Lungs are very important because Oxygen, a basic gas, is needed by every cell in your body in order to live. The air that comes into the body through the lungs contains oxygen and other gases. In the lungs, the oxygen is moved into the bloodstream and carried through the body. At each cell in the body, the oxygen cells are exchanged for waste gas called carbon dioxide. The bloodstream then carries this waste gas back to the lungs where the waste gas is removed from the blood stream and then exhaled from the body. This vital process, called gas exchange, is performed automatically by the lungs and respiratory system. Addition to gas exchange, the respiratory system performs other roles important to breathing. These include: Bringing air to the proper body temperature, moisturizing the inhaled air to the right humidity, protecting the body from harmful substances. This is done by coughing, sneezing, filtering, or swallowing them, the sense of smell. Taking good care of yourself every day will help keep your lungs healthy. Good health habits like eating a balanced diet, exercising and reducing the stress in your life will help you breathe easier. These are the steps and ways on how the lungs work. They are very important and we need them for everyday life.
