Respiratory System Organs - INI

The organs of the respiratory system are structures responsible for the process from air inhalation to gas exchange and exhalation. Divided into the upper respiratory tract (nasal cavity, pharynx, larynx) and lower respiratory tract (trachea, bronchi, lungs), each performs functions such as filtration, humidification, warming, and gas exchange. Through the coordinated work of these organs, the supply of oxygen essential for life and the removal of carbon dioxide are accomplished.
