Pulmonary System Functions and Structure

The pulmonary system provides gas exchange, regulates blood pH, contains receptors for smell, filters air, produces vocal sounds, and excretes water and heat.
Ventilation involves the transport of oxygen and carbon dioxide into and out of the lungs, while respiration is the exchange of gases across specific interfaces.
Functionally, the pulmonary system is divided into the conduction zone (nose, pharynx, larynx, trachea, bronchi, terminal bronchioles) and the respiratory zone (respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli).
Structurally, it consists of the upper respiratory system (nose, pharynx, larynx) and the lower respiratory system (trachea, bronchi, bronchioles, alveoli).
The nose filters, warms, and humidifies air, while the pharynx serves as a conduit for air and food.
The larynx connects the pharynx to the trachea, contains vocal folds, and prevents food from entering the lower pulmonary tract.
The larynx includes various cartilages such as thyroid, cricoid, arytenoid, corniculate, cuneiform, and epiglottis.
The trachea is a flexible tube with C-shaped cartilaginous rings, dividing into left and right main stem bronchi at the carina, and cleans, warms, and moistens incoming air.
The tracheobronchial tree has 23 generations, including the conducting zone (main bronchi, lobar bronchi, segmental bronchi, terminal bronchioles) and the respiratory zone (respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli).
