3. The pleural reflection
The dome of pleura, the sternal and costal lines of reflection are clinically important.
mediastinum 5. The contents of superior mediastinum. 6. Boundaries and contents of the ductus
arteriosus triangle
Chapter 3 The thorax胸部
Consist of : Thoracic wall 胸壁 Thoracic cavity胸腔
The line of pleural reflection includes: The anterior margin The posterior margin The inferior margin
3. The pleural reflection
Anterior margin formed:
It is different from thoracic cavity.
2. The pleural cavity胸膜腔
Features :
During quiet breathing, the pleural pressure is negative, and it is below atmospheric pressure.
Section 1 The thorax
Thoracic cavity胸腔
Formed by thoracic cage

1. Introduction
Lies near the center of the medial surface of the lung.
Structures at the hilum including :The bronchi 支气管, Pulmonary vessels, Bronchial vessels, Lymph vessels, Nerves enter and leave the lung
