1) " Pulmonary" -- As it applies to Pulmonary Test The heart and lungs (from an older edition of Gray's Anatomy) The lung is an organ belonging to the respiratory system and interfacing to the circulatory system of air-breathing vertebrates. Its function is to exchange oxygen from air with carbon dioxide from blood. The processin which this happens is called " external respiration " or breathing. Thereare also nonrespiratory functions of the lungs. Medical terms related to the lung often start in pulmo- from the Latin word pulmones for lungs. Contents 1 Mammalian lungs 1.1 Location 2 Evolutionary origins 3 Arachnid lungs 4 Nonrespiratory functions of the lungs 5 See also 6 External links Mammalian lungs The lungs of mammalis have a spongy texture and are honeycombed with epithelium having a much larger surface area in total than the outer surface area of the lung itself. The lungsof humans are typical of this type of lung. Breathing is largely driven by the diaphragm below, amuscle that by contracting expands the cavity in which the lung is enclosed. The rib cage itself is also able to expand andcontract to some degree. As a result, air is sucked into and pushed out of the lungs through the trachea and the bronchial tubes or bronchi; these branch out and end in alveoli which are tiny sacs surrounded by capillaries filled with blood. Here oxygen from the air diffuses into the blood, where it is carried by hemoglobin. The deoxygenated blood from the heart reaches the lungs via the Pulmonaru artery and, after having been oxygenated, returns via the Pulonary veins. Location The lungs are located inside the thoracic cavity, protected by thebony structure of the rib cage and enclosed by a double-walled sac called pleura. The inner layer of the sac adheres tightly to the outside of the lungs and the outerlayer is attached to the wall of the chest c...
