Detailed explanation-1: -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 main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.
Detailed explanation-3: -Windpipe (trachea) Large airways (bronchi) Small airways (bronchioles) Lungs.
Detailed explanation-4: -The right and left lung anatomy are similar but asymmetrical. The right lung consists of three lobes: the right upper lobe (RUL), the right middle lobe (RML), and the right lower lobe (RLL). The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL).
