MICROANATOMY

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: -Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe). Trachea: Passage connecting your throat and lungs. Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung. Lungs: Two organs that remove oxygen from the air and pass it into your blood.

Detailed explanation-3: -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.
