The lungs are held to the thorax wall by the smooth muscles of the lungs. True or False

False.

Explanation:

The lungs are a pair of pyramid shaped organs which are in between the trachea and the left bronchi and connected to both. The diaphragm is a little above them. The lungs are enclosed by the pleurae which are together with the mediastinum. The mesothelial cells which belong to the pleural membrane, make pleural fluid that can work as a lubricant to reduce friction when breathing and as an adhesive to hold the lungs to the thoracic wall which is meant to facilitate the position and movement of the lungs during ventilation.
