Study Notes

Lungs

The lungs are paired organs, situated in the thorax.
The lung (pulmo) is roughly conical.
The apex lies superiorly.
The base is inferiorly, resting on the diaphragm.
The right lung (pulmo dexter) is broader and shorter than the left.
The left lung (pulmo sinister) is narrower and more elongated, having a cardiac notch.
The lobes are separated by fissures.
The right lung has three lobes (superior, middle, and inferior).
The left lung has two lobes (superior and inferior), with an additional lingula lobe.
The fissures and their relation to the lobes are clearly presented.
The lung surfaces are labelled, including costal, diaphragmatic, and mediastinal surfaces.
The hilum is the region where the bronchi, blood vessels, lymph vessels, and nerves enter or leave the lung.
The mediastinum is the space between the lungs that separates them.
The superior mediastinum lies above the pericardium and contains the thymus and the major and minor vessels.
The inferior mediastinum is below and between the lungs.

Trachea and Bronchi

The trachea is a reinforced tube, reinforced by cartilage rings.
The trachea originates from the larynx and bifurcates into two main bronchi.
The right and left bronchi further branch into smaller branches.
The tracheal cartilages are C-shaped, incomplete posteriorly, and complete anterior and lateral.
The bronchi are also supported by cartilaginous rings of varying characteristics.
The mucous membrane lining the trachea and bronchi.
