Detailed explanation-1: -The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

Detailed explanation-2: -The main organ of the respiratory system is the lungs. Other respiratory organs include the nose, the trachea and the breathing muscles (the diaphragm and the intercostal muscles).

Detailed explanation-3: -The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs. Air enters the respiratory system through the nose or the mouth.

Detailed explanation-4: -Your lungs are on each side of your heart, inside your chest cavity. They are the main organs of the respiratory system.

Detailed explanation-5: -The respiratory portion of the lung consists of respiratory bronchiole, alveolar duct, alveolar sac, and finally alveoli where actual respiration takes place. In the conducting zone, the air is moistened, warmed, and filtered before it reaches the start of the respiratory region at the respiratory bronchioles.
