*The left and right lungs lie within their pleural sac and are only attached by their roots, to the [[Mediastinum - Anatomy & Physiology|mediastinum]], so they are fairly free within the thoracic cavity.

*The right lung is always larger than the left, due to the positioning of the heart. The apex of the lungs is the cranial point.
