Torso is an anatomical term for the central part of the many animal bodies (including that of the human) from which extend the neck and limbs. It is sometimes referred to as the trunk. The torso includes the thorax and abdomen.

respiratory system generally includes tubes, such as the bronchi, used to carry air to the lungs, where gas exchange takes place. A diaphragm pulls air in and pushes it out. Respiratory systems of various types are found in a wide variety of organisms.

The human lungs are the human organs of respiration.

Humans have two lungs, with the left being divided into two lobes and the right into three lobes. Together, the lungs contain approximately 1500 miles (2,400 km) of airways and 300 to 500 million alveoli, having a total

Right lung is divided into three lobes, superior, middle, and inferior, by two interlobular fissures:

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.

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.

lingula is used to denote a projection of the upper lobe of the left lung that serves as the homologue, and some sources define this as a distinct lobe.

There are two bronchopulmonary segments of the lingula: Superior and inferior.

The apex of the lung is rounded, and extends into the root of the neck, reaching from 2.5 to 4 cm. above the level of the sternal end of the first rib.

A sulcus produced by the subclavian artery as it curves in front of the pleura runs upward and lateralward immediately

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 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

cardiac notch, in which the pericardium is exposed. Opposite this notch the anterior margin of the left lung is situated some little distance lateral to the line of reflection of the corresponding part of the pleura.

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

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. These include the pulmonary artery, superiormost on the left lung, the superior and inferior pulmonary veins, and

The anterior border of the lung is thin and sharp, and overlaps the front of the pericardium.

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,

The posterior border of the lung is broad and rounded, and is received into the deep concavity on either side of the vertebral column.

It is much longer than the anterior border, and projects, below, into the phrenicocostal sinus.

In the lung, the oblique fissure (or major fissure) separates the inferior lobe of either lung from the remainder of the lung. (In the right lung, it separates it from the middle and superior lobe; in the left lung it separates it from the superior lobe, as there is no

The horizontal fissure of right lung (or transverse fissure) is a fissure separating the superior lobe from the middle lobe.

The left lung has no middle lobe, so there is no horizontal fissure on that lung.

The conducting zone of the respiratory system is made up of the trachea, bronchi, bronchioles, and terminal bronchioles.

The conducting zone represents the 1st through the 16th division of the respiratory tract.

trachea, or windpipe, is a tube that has an inner diameter of about 20-25 mm and a length of about 10-16cm. It extends from the larynx to the primary (main) bronchi in mammals, and from the pharynx to the syrinx in birds, allowing the passage of air to the lungs.

The cartilages of the trachea (or tracheal rings) vary from sixteen to twenty in number: each forms an imperfect ring, which occupies the anterior two-thirds or so of the circumference of the trachea, being deficient behind, where the tube is completed by fibrous tissue and
