Lung Lobe Anatomy

Gross anatomy of the lungs. Superior middle and inferior.

On the inferior surface the lungs are bordered by the diaphragm.

Lung lobe anatomy. The right upper lobe of the lung is one of the three lobes that make up the right lung. The oblique fissure in the left lung separates the superior and the inferior lobe. In the right lung there is an oblique fissure and a horizontal fissure separating the lung into three lobes upper middle and lower.

It is divided into three lobes an upper middle and a lower lobe by two fissures one oblique and one horizontal. The left lung is divided into two lobes upper and lower. The lobes are divided from each other by two fissures.

Each lung is divided into lobes by fissures. The right upper lobe of the lung is located in the right superior corner of the thoracic cavity lateral to the trachea and esophagus. The upper horizontal fissure separates the upper from the middle lobe.

Oblique fissure runs from the inferior border of the lung in a superoposterior direction until it meets the posterior lung border. Both lungs have oblique fissure and the right is further divided by a transverse fissure. The oblique and horizontal fissure divides the lungs into superior middle and inferior lobes.

Each lobe again has its own visceral pleural covering. These lobes have their own pleural covering and these lie together to form the oblique major fissure. The upper lobes contains 3 segments the middle lobe lingula 2 and the lower lobes 5.

The lungs are pyramid shaped paired organs that are connected to the trachea by the right and left bronchi. The diaphragm is the flat dome shaped muscle located at the base of the lungs and thoracic cavity. The right and left lungs do not have an identical lobular structure.

This is in contrast to the much smaller lobule which is a clear division only visible under the microscope. In general each lung has 10 segments. The right lung has three lobes.

Bilaterally the upper lobes have apical posterior and anterior segments and the lower lobes superior apical and 4 basal segments anterior medial posterior and lateral. In anatomy a lobe is a clear anatomical division or extension of an organ as seen for example in the brain lung liver or kidney that can be determined without the use of a microscope at the gross anatomy level. The lung tissue of this lobe is responsible for most of the gas exchange in the right lung during calm shallow breathing.

The right lung has both more lobes and segments than the left. The lobes are further separated into smaller segments with the right lung having 10 segments and the left lung having 9 2.
