The lungs are a pair of organs in the thoracic cavity marking the terminal portion of the respiratory apparatus. Their main function is breathing, enabling the exchange of oxygen and carbon dioxide. The inhaled air reaches the lungs from the upper respiratory tract via the nasal cavity, pharynx, larynx, trachea, bronchi and the bronchioles.
The right and left lungs slightly differ in their macroscopic structure: The right lung is larger in size and has three lobes, whereas the left lung only has two, due to the close proximity to the heart. Each lung has three surfaces:
- Costal surface
- Mediastinal surface
- Diaphragmatic surface
In this video tutorial we will explore the anatomy and topography of the lung and the differences between the right and left lung:
- 0:16 right and left lung lobes
- 0:44 horizontal and oblique fissure
- 1:06 surfaces of the lung
- 1:38 respiratory epithelium
