Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ...
Fissures - One of these, the oblique fissure, separates the inferior from the middle and superior lobes, and corresponds closely with the fissure in the left lung. Its direction is, however, more vertical, and it cuts the lower border about 7.5 cm. behind its anterior extremity.
In the lung, the oblique fissure (or major fissure) separates the inferior lobe of either lung from the remainder of the lung. ...
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 horizontal fissure of right lung (or transverse fissure) is a fissure separating the superior lobe from the inferior lobe. ...
The anterior border of the lung is thin and sharp, and overlaps the front of the pericardium. ...
The costal cartilages are bars of hyaline cartilage which serve to prolong the ribs forward and contribute very materially to the elasticity of the walls of the thorax. ...
A hilum (formerly called a hilus) is a depression or pit at the part of an organ where structures such as blood vessels and nerves enter. ...
Lobes The middle lobe, the smallest lobe of the right lung, is wedge-shaped, and includes the lower part of the anterior border and the anterior part of the base of the lung. (There is no middle lobule on the left lung, though there is a lingula. 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. ...
According to most sources, there is no middle lobe in the left lung as there is in the right lung. ...
The superior and inferior lobes are similar to their counterparts on the left lung. 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. ...
Difference in size The right lung, although shorter by 2.5 cm. than the left, in consequence of the diaphragm rising higher on the right side to accommodate the liver, is broader, owing to the inclination of the heart to the left side; its total capacity is greater and it weighs more than the left lung. A diaphragm is some sort of separating membrane. ...
The liver is the largest internal organ of the human body. ...
Impressions On the mediastinal surface, immediately above the hilus, is an arched furrow which accommodates the azygos vein; while running upward, and then arching lateralward some little distance below the apex, is a wide groove for the superior vena cava and right innominate vein; behind this, and nearer the apex, is a furrow for the innominate artery. The azygos vein is so named because it is unpaired, having no matching vein on the left side of the body. ...

The Brachiocephalic vein is also known as the innominate vein, the left and right brachiocephalic veins in the upper chest are formed by the union of each corresponding jugular vein and subclavian vein. ...
The brachiocephalic artery (or trunk) is an artery of the mediastinum that supplies blood to the right arm and the head. ...
Behind the hilus and the attachment of the pulmonary ligament is a vertical groove for the esophagus; this groove becomes less distinct below, owing to the inclination of the lower part of the esophagus to the left of the middle line. The root of the lung is covered in front, above, and behind by pleura, and that at its lower border the investing layers come into contact. ...
The esophagus (also spelled oesophagus/Å“sophagus), or gullet is the muscular tube in vertebrates through which ingested food passes from the mouth area to the stomach. ...
In front and to the right of the lower part of the esophageal groove is a deep concavity for the extrapericardiac portion of the thoracic part of the inferior vena cava. This article may be too technical for most readers to understand. ...

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. ...
According to most sources, there is no middle lobe in the left lung as there is in the right lung. ...
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. ...
