lungs: right, left, lingula, apex, base, root, cardiac notch, cardiac impression, hilum, borders (anterior, posterior, inferior), surfaces (costal, mediastinal, diaphragmatic), fissures (oblique, horizontal) The lungs flank the heart and great vessels in the chest cavity. ... The lungs flank the heart and great vessels in the chest cavity. ... The left lung is divided into two lobes, an upper and a lower, by the oblique fissure, which extends from the costal to the mediastinal surface of the lung both above and below the hilus. ... The apex of the lung is rounded, and extends into the root of the neck, reaching from 2. ... The base of the lung is broad, concave, and rests upon the convex surface of the diaphragm, which separates the right lung from the right lobe of the liver, and the left lung from the left lobe of the liver, the stomach, and the spleen. ... The anterior border of the right lung is almost vertical, and projects into the costomediastinal sinus; that of the left lung presents, below, an angular notch, the cardiac notch, in which the pericardium is exposed. ... The mediastinal surface of the lung presents a deep concavity, the cardiac impression, which accommodates the pericardium; this is larger and deeper on the left lung than on the right lung, on account of the heart projecting farther to the left than to the right side of the median plane. ... Above and behind the cardiac impression is a triangular depression named the hilum, where the structures which form the root of the lung enter and leave the viscus. ... The anterior border of the lung is thin and sharp, and overlaps the front of the pericardium. ... The inferior border of the lung is thin and sharp where it separates the base from the costal surface and extends into the phrenicocostal sinus; medially where it divides the base from the mediastinal surface it is blunt and rounded. ... The costal surface of the lung (external or thoracic surface) is smooth, convex, of considerable extent, and corresponds to the form of the cavity of the chest, being deeper behind than in front. ... The diaphragmatic surface of lung is the portion of the lung which borders on the thoracic diaphragm. ... The horizontal fissure of right lung (or transverse fissure) is a fissure separating the superior lobe from the inferior lobe. ...

airway: trachea, carina, bronchi, main bronchus (right, left), lobar/secondary bronchi (eparterial bronchus), segmental/tertiary bronchi (bronchopulmonary segment), bronchiole, alveolar duct, alveolus Windpipe redirects here. ... In anatomy, the carina is a cartilaginous ridge in the sagittal plane of the trachea where it splits into the two primary bronchi. ... A bronchus (plural bronchi, adjective bronchial) is a caliber of airways in the the respiratory tract that conducts air into the lungs. ... The Respiratory system is a very important part of the human body. ... A bronchus (plural bronchi, adjective bronchial) is a caliber of airway in the respiratory tract that conducts air into the lungs. ... Secondary bronchi (also known as lobar bronchi) arise from the primary bronchi, with each one serving as the airway to a specific lobe of the lung. ... The right bronchus gives off, about 2. ... The tertiary bronchi (also known as the segmental bronchi) arise from the secondary bronchi. ... Each of the tertiary bronchi serves a specific bronchopulmonary segment. ... The bronchioles are the first airway branches that no longer contain cartilage. ... Alveolar ducts are the tiny end tubules of the branching airways that fill the lungs. ... Detailed drawing of the alveoli from Grays Anatomy, 1918 - Schematic longitudinal section of a primary lobule of the lung (anatomical unit); r. ...

pleurae: parietal pleura (cervical, costal, mediastinal, diaphragmatic), pulmonary pleura, pulmonary ligament, recesses (costomediastinal, costodiaphragmatic) In anatomy, the pleural cavity is the potential space between the lungs and the chest wall. ... The portion of the pleura external to the pulmonary pleura lines the inner surface of the chest wall, covers the diaphragm, and is reflected over the structures occupying the middle of the thorax; this portion is termed the parietal pleura. ... Different portions of the parietal pleura have received special names which indicate their position: thus, that which rises into the neck, over the summit of the lung, is the cupula of the pleura (cervical pleura). ... Different portions of the parietal pleura have received special names which indicate their position: thus, that portion which lines the inner surfaces of the ribs and Intercostales is the costal pleura. ... Different portions of the parietal pleura have received special names which indicate their position: thus, that portion which lines the inner surfaces of the ribs and Intercostales is the costal pleura; that clothing the convex surface of the diaphragm is the diaphragmatic pleura; that which rises into the neck, over... Different portions of the parietal pleura have received special names which indicate their position: that clothing the convex surface of the diaphragm is the diaphragmatic pleura. ... The costomediastinal recess is a potential space at the border of the mediastinal pleura and the costal pleura. ... In the pleural cavity, the costodiaphragmatic recess is a potential space at the posteriormost tips of the cavity, located at the junction of the costal pleura and diaphragmatic pleura. ...
