In man, the lungs are paired organs of respiration in the thoracic cavity. They have the shape of a half cone with a rounded apex and a concave base (which is a function of the shape of the diaphragm). The inner, or medial, surface of the lung faces the heart and is the site of...
Since gas trapping and airway closure are related, there could also be intrinsic dissimilarities in airway closure between the apex and base of excised rat lungs suspended by the trachea in air.doi:10.1016/0034-5687(84)90053-7J.J. Morgan...
point of the cone and the inferior end forming the base. The superior end of the lungs narrows to a rounded tip known as theapex. The inferior end of the lungs, known as thebase, rests on the dome-shapeddiaphragm. The base of the lungs is concave to follow the contour of the ...
Base 3 edges (anterior, posterior, and inferior) 2 surfaces (costal and medial) Anatomical Position And Side Decision The side of lung can be decided by holding the lung in this manner that:. Its conical end (apex) is pointed upwards and its wider end (base) is pointed downwards,. Its...
Structure and Anatomy of the Lungs Each lung has an apex, base, root, and hilum or hilus of the lung, as well as three surfaces, keeping the lung connected to the sides of the thorax [7]. The apexis the superior part of the lungs, with its highest point located above the first rib...
The hilum, located about two-thirds of the way from the base to the apex of each lung, is the place at which the bronchi, pulmonary arteries and veins, lymphatic vessels, and nerves join the lung. After reaching your lung, the primary bronchus splits several times, culminating in an ove...

The lungs were inflated to 10 cmH2O pressure and a gradient of transmural vascular pressure of 0-17 cm , from lobe base to apex, was established in the -filled vascular system. Histological materials were obtained after airway fixation by solution and analyzed for vessel diameter in the ...
