PATHOLOGY

Detailed explanation-1: -The respiratory system takes up oxygen from the air we breathe and expels the unwanted carbon dioxide. 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-2: -The lungs are the largest organ of the respiratory system. The respiratory system supplies the oxygen needed by the cells of the body and takes away the waste carbon dioxide.

Detailed explanation-3: -You have two lungs, the left lung and the right lung. The left lung is slightly smaller and has a notch to give room for the heart. Each lung is divided into lobes-the left lung has two and the right lung has three-which are similar to balloons filled with sponge-like tissue.
