Ch 2 Body Cavities Flashcards
(28 cards)
Compartment housing specific organs
Body Cavity
Function of Body Cavity
Protect and permit change (size/shape)
Body cavity lining (provides fluid to reduce friction)
serous membranes
Membrane associated with the heart
Pericardium
Membrane associated with the lungs
Pleura
Membrane associated with the abdominal organs
peritoneum
Two layers of membranes
parietal and visceral
Parietal layer
membrane lining cavity
visceral layer
membrane covering organ
dorsal cavity contains
cranial and vertebral cavity
two main body cavities
dorsal and ventral
ventral body cavity contains
thoracic and abdominopelvic separated by diaphragm
thoracic cavity
above diaphragm. holds right and left pleural cavities. lined by pleura
pleural cavities are lined by
parietal pleura (outer) and visceral pleura (inner)
area in between pleural cavities
mediastinum
superior mediastinum
blood vessels, trachea, esophagus, and thymus
inferior mediastinum
pericardial cavity (location of heart)
pericardial cavity is lined by
parietal pericardium and visceral pericardium
abdominopelvic cavity
below diaphragm. holds peritoneal cavity and retroperitoneal space.
peritoneal cavity
within abdominopelvic cavity. lined by parietal and visceral peritoneum
parietal peritoneum
lines internal body wall
visceral peritoneum
covers organs
serosa
outermost layer of GI tract in peritoneal cavity
space behind peritoneal cavity
retroperitoneal space
