RACK 2 THORAX

The right and left lungs differ in size and shape to accommodate other organs that encroach on the thoracic region. The right lung consists of three lobes and is shorter than the left lung, due to the position of the liver underneath it. The left lung consist of two lobes and is longer and narrower than the right lung.

Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes. As the bronchi branch out, the total area of the two new branches is larger than its parent bronchus, making it extremely easy for the air to rush into the lungs.

he right lung consists of three lobes: the right upper lobe (RUL), the right middle lobe (RML), and the right lower lobe (RLL). The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL).

lungs make up a large part of your respiratory system, which is the network of organs and tissues that allow you to breathe. You have two lungs, one on each side of your chest, which is also called the thorax. Your thorax is the area of your body between your neck and your abdomen

The lung root on the left is ensheathed by the pulmonary ligament which hangs inferiorly. The relations of the root to landmarks on the surface of the lung is described in the submenu on the mediastinal surface. The left-sided lung root is approximately triangular in shape with the apex pointing posteroinferiorly.

When an unborn baby's lungs form during pregnancy, they grow in parts called lobes. Each lobe connects to the airway so air can move in and out of it when the baby starts breathing after birth. A fetal lung mass can cause problems before the baby is born if it gets big enough to put pressure on: other parts of the lung.

The costal surface is covered by the costal pleura and is along the sternum and ribs. It also joins the medial surface at the anterior and posterior borders and diaphragmatic surfaces at the inferior border. The medial surface is divided anteriorly and posteriorly.

The left lung does not have a middle lobe in contrast to the right lung, however it does have a projection of the upper lobe called lingula. The lingula on the left lung is as the same as the middle lobe in the right lung.
