Lungs and Chest Wall (Ch. 2) - Respiratory Care Anatomy and Physiology,3rd Ed rated A+ ever Costal - Rib Mediastinum - Central portion of the chest cavity containing the heart, aorta, esophagus, great veins, trachea, and mainstem bronchi. Cardiac Notch - Anterior border of the left lung accommodating the protrusion of the heart Diaphragm - Major muscle of ventilation; Separates the thoracic and abdominal cavities Hilum (of the lung) - Area on the lung's mediastinal surfaces through which arteries, veins, and the main bronchus enter Lingula - Tongue-like anatomical counterpart of the middle lobe of the right lung Visceral pleura - Membrane forming a sealed envelope around and attached to the lung's surface Parietal pleura - Continuous of the visceral pleura and attached to the inner chest wall surface Pleural space - Potential space between the visceral and parietal membrances Intrapleural pressure - Pressure between the pleural membranes; sub-atmospheric during normal breathing Costophrenic recess - Area in which the lowest margin of the diaphragm meets the chest wall Pleural effusion - Fluid formed in the pleural space, settling in the costophrenic recesses Thoracentesis - Removal of fluid in the thoracic cavity by way of syringe and large-gauge needle Anastosome - Typically a tubular connection between two structures, i.e. the bronchopulmonary-arterial anastosome Pneumothorax - Air in the thoracic cavity (pleural space) Anatomical shunt - A normal flaw through which oxygen-poor blood mixes with oxygen-rich blood going back into circulation via the bronchopulmonary-arterial anastosomes
