The pulmonary system is made up of the upper and lower airways, the chest wall, and pulmonary circulation. Its main function is to exchange gases between the blood and the air in the environment.
Here are some structures of the pulmonary system: Trachea: A passageway for air to enter and exit the lungs, surrounded by cartilage rings Larynx: An organ that controls the access to the lungs as an air canal and produces sound by forcing air through the vocal cords Pharynx: A tube-like structure that connects the nasal cavity to the larynx and other structures in the throat, and allows air and food to pass through Bronchus: A structure that helps bring air in and out of the lungs, dividing into secondary, tertiary, and smaller tubes called bronchioles Lung lobes: Segments that define the lung's surface, with the left lung having two lobes and the right lung having three Diaphragm: A dome-shaped muscular structure that regulates air pressure in the thoracic chamber Pleura: A double-layered membrane that acts as a cushion for the lungs Pulmonary arteries: Transport oxygen from the blood to other parts of the body
