Lower Respiratory Tract Illustrations and Animations

The lower respiratory tract category covers the airway from the trachea to the alveoli. Assets include the trachea, the bronchi and bronchioles, the lungs with their lobes and bronchopulmonary segments, the alveoli, the pleura, and the diaphragm. Structures are available as whole-lung views, coronal and sagittal thoracic sections, and isolated bronchial tree and alveolar renderings that show gas-exchange detail. Every asset is rendered from one labeled 3D model built to Terminologia Anatomica and reviewed by our Medical Advisory Board, so airway and lung anatomy stays consistent from the trachea to the alveoli. The collection supports pulmonology and physiology education, patient communication, pharmaceutical and medical device content, and editorial use. Assets are available as high-resolution illustrations and 3D animations, licensed under Educational, Standard, or Extended terms through a subscription with credits or as individual purchases.

“I have been teaching school children of all ages about heart health and disease in February, heart month, since 2016, and I am so excited to use the exceptional images from Sciepro.com. The images are stunningly realistic and accurate and really help me to teach about heart health. They also show how the heart relates to its neighboring organs, and there are images that depict the initiation and progression of atherosclerosis.”
