Breathing.–Respiration, or the act of breathing, consists of thealternate inspiration and expiration of air to and from the lungs; in the process of which the lungs themselves are almost passive managements, since their contraction expansion takes place by means of the muscles which surround the chest. The diaphragm or midriff, which, when at rest in […]

Lung Air Cells.  — Each air cell varies in size from the seventieth to the one two-hundredth parts of an inch in diameter.  The number of aerosols in the two lungs is truly surprising, they’re been certainly not less than 600,000,000, though according to Dr. Addison’s computation there are 1,700,000,000, equivalent to 1,500 square feet […]

Interior Arrangement of Lungs. — On turning this flap over we find a vertical section of lungs, showing their anterior arrangements. The lower end of the trachea divides, one portion going to each long. These again subdividing continue to subdivide in geometrical order, growing smaller and smaller with each division, and extending […]

Pleura of the Lungs. –in this chart we see also the pleura or the investing membrane of the lungs, and right below it the diaphragm or midriff.Two Distinct Lungs. –although the lungs are two in number, as far as their structure is concerned, and are perfectly distinct from each other, having, as we observe in […]
