2. INTRODUCTION
Lungs are a pair of muscular respiratory organs that
facilitates gaseous exchange . Right and left lung are

Colour : in young :Brown
in adults :Molten black
Weight: Right : 700 g
Left : 600-650g
Capacity: 6L

3. LOCATION AND SURFACE MARKING
• The lungs lie in the thoracic cavity.

4. EXTERNAL FEATURES
• Apex
• Base
• 3 Borders: Anterior
Posterior
Inferior
• 2 Surfaces: Costal
Medial (divided into vertebral and mediastinal parts)

5. FISSURES AND LOBES
RIGHT LUNG: 3 Lobes divided by 2 fissures
- Upper -Oblique
-Middle -Horizontal
-Lower
LEFT LUNG: 2 Lobes divided by the oblique fissure.

7. ROOT OF LUNG
 Connects medial surface of the lung to the mediastinum.
 Lie opposite the bodies of 5th , 6th and 7th vertebrae.
