Body Cavities (Lateral View) Cranial Cavity Vertebral Cavity Thoracic Cavity Diaphragm Abdominal Cavity Pelvic Cavity

Body Cavities (Anterior View) Cranial Cavity Vertebral Cavity Pelvic Cavity Abdominal Cavity Diaphragm Pleural Pericardial Cavity Thoracic Cavity Mediastinum

Membranes/ Serous Membranes
Soft, thin, pliable double-layer of tissue that covers organs or lines body cavities
Cavity lining = parietal serosa
Organ lining = visceral serosa
Serous fluid
