plueral space
The space between the lungs in the chest is called the mediastinum. Its function is to house and protect vital organs such as the heart, major blood vessels, esophagus, trachea, and lymph nodes. It also allows for the passage of nerves and blood vessels to and from the upper body.
The potential space between the lining of the chest cavity (pleura) and the lining that covers the lungs (also called the pleura). These linings are made of serous membranes that secrete serous fluid for lubrication, so there is no friction during breathing when the lungs expand and contract against the chest wall. There is a vacuum maintained in this space that keeps the lungs inflated.
The pleural space is located between the two layers of the pleura, which are thin membranes that surround the lungs. The visceral pleura is the inner layer that covers the lung, and the parietal pleura is the outer layer that lines the chest cavity. The pleural space contains a small amount of fluid that helps reduce friction during breathing.
The space between the breasts is called the cleavage.
