is split by the diaphragm
what is in the thoracic cavity
- right and left pleural cavities: which hold each lung
- mediastinum

no distinct barrier between the 2
in order to create the body’s cavities within our bodies what do we have to border the space
membranes
what membrane lies atop of the organs which makes direct contact with them
the visceral membrane
what are some ex of visceral membranes
- visceral pericardium: outermost layer of the heart
- visceral pleura: on the lungs
what membrane lies on the other side of the spaces or lining of the cavity itself
the parietal membrane
what is an ex of a parietal membrane
parietal peritoneum: lining of the abdominopelvic cavity
the other parts of the body are divided into
- axial areas
- appendicular areas
the axial portions are the part of your body that form your axis like the
