Body cavities and serous membranes Flashcards
mediastinum
center of thoracic cavity, contains all organs between the lungs
pleural cavity
-each pleural cavity contains one lung, encased by pleura

- in the mediastinum
- contians heart
- encased in pericardium
abdominal cavity
- contains digestive organs
- encased by peritoneum
pelvic cavity
- contains bladder and reproductive organs
- encased in peritoneum
Dorsal body cavities
cranial cavity
spinal cavity
cranial cavity
- contains brain
- protected by meninges
spinal cavity
- contains spinal cord
- protected by meninges
ventral body cavities
- thoracic cavity
- diaphragm
- abdominopelvic cavity
diaphragm
-separates thoracic and abdominopelvic cavities
pleura
- parietal layer
- visceral layer
parietal layer
-lines the thoracic cavity
visceral layer
-lies directly on surface of lungs
pericadium
- in thoracic cavity
- encases the heart
pericadium: parietal layer
- forms tough, outer sac
- also called pericardial sac
pericardium: visceral layer
- fused directly to surface of heart
- also called epicardium
peritoneum
- in abdominopelvic cavity
- encases the abdominal and pelvic organs
mesentary
- fold of peritoneum
- suspends and attaches organs to body wall
