Introduction

LUNG

  • The lungs is a paired organ covered with the pleura.
  • Located in the pleural cavity.
  • Responsible for oxygenating blood that enters via the pulmonary artery and leaves via the pulomanry vein.
  • The color of the healthy lung ranges from gray to bluish - pink.

Parts of the lung:

  1. Base of lung (basis pulmonis) – the concave base resting on the diaphragm
  2. Apex of lung (apex pulmonis) – projects towards the cervical pleura
  3. Hilum of lung (hilum pulmonis)
  • a place where the structures of the root of the lung enter the lung
  1. 4 Root of lung (radix pulmonis)
  • the vessels, lymphatics, nerves, and bronchi passing through the hilum
  1. 5 Pulmonary ligament (ligamentum pulmonale) – a caudally extending pleural fold
  • a transition between the parietal and visceral pleura
  1. 6 Lingula of left lung (lingula pulmonis sinistri)
  • a thin slip of pulmonary tissue extending from the upper lobe of the left lung
  • the analogue of the middle lobe on the right lung
  • → Forms part of the base
