It's too late for me but stretch marks are perfectly preventable (sometimes, though, whatever you do you still get them) so here are some tips I give to my friends: Maintain a healthy skin. Drink lots of water (at least 2 litres every day) - not soda or juices - because it helps your skin stay elastic.

The pericardium lies within the mediastinum, the portion of the thoracic cavity between the left and right pleural cavities (Figure 1-11d). The connective tissue of the mediastinum surrounds the pericardial cavity and heart, the large arteries and veins attached to the heart, and the thymus, trachea, and esophagus.he thoracic cavity contains three internal chambers: a single pericardial cavity and a pair of pleural cavities (Figure 1-11a). These cavities are lined by shiny, slippery serous membranes. The heart is surrounded by the pericardial cavity.
