Dynamic MSCT shows the lunate configuration of the trachea during forced expiration in one patient with tracheomalacia. In one patient with tracheo-esophageal fistula, the extent of fistulous tract and the resulting bronchial aspiration were demonstrated. MSCT proved to be indispensable as a ...
Surround the bronchial tree Enclosed within the visceral pleura Attached to the trachea via the main bronchi of the tracheobronchial tree Attached to the heart via pulmonary vessels Basic structure: Each lung has a base, apex, 2 surfaces, and 3 borders: The base sits on the diaphragm ...
X-ray of the bronchial tree 支气管树的X射线图像 A branching system of tubes carries air all through the lungs. The trachea divides into two bronchi, one to each lung. Each bronchus splits into many smaller bronchi, then bronchioles, and finally terminal bronchioles, narrower than a hair. ...
Carbon dioxide from the body is released into the lungs via ___. a. ciliated mucous membrane b. alveolar air c. nasal cavity d. bronchial tree If some capillaries in the lungs are collapsed, what is the functional effect on the diffusion of O_2 and CO_2? Which...
The lungs passively expand, and negative pressure within the lungs draws air in through the pharynx, larynx, trachea, and bronchial tree. What is the role of negative pressure within the thoracic cavity? It pulls air into the lungs and can also pull in other substances (e.g., air, blood...

Explain the structure and function of the respiratory membrane. Explain the structure and function of the parts of the respiratory system. Describe the anatomy and physiology of the trachea, bronchial tree, alveolar sacs, and alveoli. Identify the organs of the respiratory system. ...
Comparative navigations were performed on three main branches of the left bronchial tree of a cadaveric specimen using the magnetic tentacle and a standard bronchoscopic catheter (Edge™ EWC Firm Tip Medial Procedure Kit, Medtronic), as shown in Fig. 4. The standard catheter was operated by an...
The respiratory system consists of a conducting zone (anatomic dead space; i.e., the airways of the mouth, nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles) and a resp...
In amphibians, the lungs, smooth-walled (in gilled animals) or alveolate pouches, begin immediately at the larynx or trachea. In lower reptiles (Gatteria), the walls of the lungs are alveolate. In some lizards (monitors), turtles, and crocodiles, the lungs have a spongy structure; in proli...
