The term 'respiratory organs' refers to the organs in the body that are responsible for breathing. The most important of these organs are the LUNGS, which are composed of five letters: LUNGS. The LUNGS are responsible for taking in oxygen from the air and releasing carbon dioxide back into the atmosphere. They also play a role in regulating the body's temperature and pH levels. Other respiratory organs include the nose, throat, trachea, bronchi, and diaphragm. Together, these organs work to ensure that the body is able to take in oxygen and expel carbon dioxide efficiently.
