The most inferior structure in right lung is pulmonary artery.

the hilum of right lung is larger than left lung.

The most superior structure in left hilum carries low oxygenated blood away from lung.

The most anterior structure in left hilum carries high oxygenated blood away from lung.

The most posterior structure in right lung is pulmonary artery.

right main bronchus is shorter, horizontal and wider.

Tertiary bronchus is relaed to the lung segments.

Left lung had 3 segmental bronchi

Left main bronchus is longer and vertical.

Lumen of bronchioles are larger than secondary bronchus.

Pulmonary veins are located in most inferior part of the hilum.

pulmonary artery leaves the hilum of lung.

Cardiac notch can be found in both two lungs.

Lingula is one of the landmaks in right lung.

Anterior borders of both lungs are same.

The parietal layer is becoming continous with visceral layer at the lung hilum.

Only visceral layer can produce the pleural fluid.

pleural cavity is located between visceral layer and diaphragmatic surface.

Both parietal and viseral laters are muscular layer.

Hilum of lung is located in costal surface of lung.
