Respiratory System. Several organs of the respiratory system are responsible for the process of breathing. The nose, pharynx, larynx, trachea, bronchi, and lungs work together to allow gas exchange to occur at the cellular level.
Upper respiratory tract: This includes the nose, mouth, and the beginning of the trachea (the section that takes air in and lets it out). Lower respiratory tract: This includes the trachea, the bronchi, broncheoli and the lungs (the act of breathing takes place in this part of the system).The organs of the lower respiratory tract are located in the chest cavity.t the same time, carbon dioxide (CO2) is transmitted from the blood capillaries into the alveoli and then expelled through the bronchi and the upper respiratory tract. The inner surface of the lungs where the exchange of gases takes place is very large, due to the structure of the air sacs of the alveoli.
