Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ...

The root is formed by the bronchus, the pulmonary artery, the pulmonary veins, the bronchial arteries and veins, the pulmonary plexuses of nerves, lymphatic vessels, bronchial lymph glands, and areolar tissue, all of which are enclosed by a reflection of the pleura. The pulmonary arteries carry blood from the heart to the lungs. ...
The pulmonary veins carry blood from the lungs to the left atrium of the heart. ...
In mammals including humans, the lymphatic vessels (or lymphatics) are a network of thin tubes that branch, like blood vessels, into tissues throughout the body. ...
The root of the right lung lies behind the superior vena cava and part of the right atrium, and below the azygos vein. That of the left lung passes beneath the aortic arch and in front of the descending aorta; the phreni pericardiacophrenic artery and vein, and the anterior pulmonary plexus, lie in front of each, and the vagus and posterior pulmonary plexus behind each; below each is the pulmonary ligament. The right lung is divided into three lobes, superior, middle, and inferior, by two interlobular 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. ...

The azygos vein is so named because it is unpaired, having no matching vein on the left side of the body. ...
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 largest artery in the human body, the aorta originates from the left ventricle of the heart and brings oxygenated blood to all parts of the body in the systemic circulation. ...
The vagus nerve is tenth of twelve paired cranial nerves and is the only nerve that starts in the brainstem (somewhere in the medulla oblongata) and extends all the way down past the head, right down to the abdomen. ...
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 chief structures composing the root of each lung are arranged in a similar manner from before backward on both sides, viz., the upper of the two pulmonary veins in front; the pulmonary artery in the middle; and the bronchus, together with the bronchial vessels, behind.
From above downward, on the two sides, their arrangement differs, thus:
On the right side their position is—eparterial bronchus, pulmonary artery, hyparterial bronchus, pulmonary veins, but on the left side their position is—pulmonary artery, bronchus, pulmonary veins.
The lower of the two pulmonary veins, is situated below the bronchus, at the apex or lowest part of the hilus.

The right lung is divided into three lobes, superior, middle, and inferior, by two interlobular 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. ...
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. ...
Above and behind the cardiac impression is a triangular depression named the hilum, where the structures which form the root of the lung enter and leave the viscus. ...
The anterior border of the lung is thin and sharp, and overlaps the front of the pericardium. ...
The posterior border of the lung is broad and rounded, and is received into the deep concavity on either side of the vertebral column. ...
The inferior border of the lung is thin and sharp where it separates the base from the costal surface and extends into the phrenicocostal sinus; medially where it divides the base from the mediastinal surface it is blunt and rounded. ...
The costal surface of the lung (external or thoracic surface) is smooth, convex, of considerable extent, and corresponds to the form of the cavity of the chest, being deeper behind than in front. ...
The mediastinal surface of the lung is in contact with the mediastinal pleura. ...
The diaphragmatic surface of lung is the portion of the lung which borders on the thoracic diaphragm. ...
In the lung, the oblique fissure (or major fissure) separates the inferior lobe of either lung from the remainder of the lung. ...
The horizontal fissure of right lung (or transverse fissure) is a fissure separating the superior lobe from the inferior lobe. ...
