THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Your mediastinum is a space in your chest that holds your heart and other important structures. It’s the middle section of your thoracic cavity, between your left and right pleural cavities (which hold your lungs). Many conditions can affect the organs and tissues in your mediastinum, including tumors and infections.

Detailed explanation-2: -Mediastinum/Heart The transversal cardiac diameter is < 14.5 cm for females and < 15.5 cm for males. Enlargement of the cardiac shadow > 1.5 cm in transverse diameter is considered significant.

Detailed explanation-3: -The mediastinum is the partition between the lungs and includes the mediastinal pleura. It is commonly applied to the internal between the two pleural sacs, the sternum and the thoracic vertebral column extending to the diaphragm.

Detailed explanation-4: -The pericardium is a double-layer-fibrous outermost layer and serous innermost layer-sac of fibroelastic/fibroserous tissue encasing the heart, anchoring it to the mediastinum (a passageway for many structures that pass through the thorax), and forming a cavity filled with a serous fluid.
