Illustrations of the Human Respiratory System

This medical illustration gallery relates to respiratory tract illustrations, the upper respiratory tract, nose and nasal passages, paranasal sinuses, the respiratory airways, the larynx, trachea, bronchi, and the lungs respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli. Created by Joanna from the medical-artist.com and the medical illustrations commissioned as part of patient educational materials.

Interesting Facts about the Respiratory System

The role of the respiratory system is to carry out the gaseous exchange between the circulatory system and the oustide air that we breath in and the lungs are the essential organs of this respiration process. Each lung is connected via the trachea or windpipe to the lungs main bronchus. Air is taken in through the upper airways such as the nasal cavity, into the lower airways of the trachea, into the primary bronchi and bronchial tree and into the small bronchioles and alveoli within the lung tissue. The purpose is so the molecules of oxygen that we have breathed in can be exchanged by a diffusion process, allowing for the gaseous exchange of air from the external environment into the blood stream. Following the same process in reverse is the expelling of carbon dioxide as a waste product.

The function of the lungs - In addition to respiratory activities, the lungs perform other bodily functions. Through them, water, alcohol, and pharmacologic agents can be absorbed and excreted. The lungs filter out small blood clots formed in veins. The lungs are also a true metabolic organ as it is involved in the synthesis, storage, transformation, and degradation of a variety of substances, including pulmonary surfactant and fibrin. The lungs secret immunoglobulin A, into the bronchial of the lung which helps to protects against respiratory infections.
