dorsal cavity
has the crainal and spinal cavities
crainal cavity
has the brain
spinal cavity
the back bone
ventral cavity
has the Thoracic and adominopelvic cavities
thoracic cavity
has the heart and lungs
Pleural cavity
has lungs
pericardial cavity
has heart
mediastinum
membranous partition that lies between the heart and lungs
abdominopelvic cavity
has abdominal and pelvic cavity
abdominal cavity
sup. portion of ab/pelvic cavity (has stomach spleen kidneys etc)
Pelvic cavity
inf. portion of ab/pelvic cavity (has urinary blader, uterus, etc.)
serous membrane
lines all body cavities and covers all internal organs
serous fluid
secreted by serous membrane, reduces friction between organs
parietal pleural
lines rib cage outside of lungs
visceral (pulmonary) pleural
membrane covering lungs
pleuriesy
inflamation of the pleural membranes
parietal pericardum
double layered loose, fibroussac, outside heart and visceral pericardum
visceral pericardium
covers heart
peritoneum membrane
lines ab/pelvic cavity
parietal peritoneum
lines abdonminal cavity
visceral peritoneum
cover internal organs in the ab cavity
mesentary
double layered folds of connective tissue that extends from post. surface of ab cavity to hald internal organs in place, contains nerves and blood vessals
greater omentum
mesentary extends downward from stomach to front of intestines, to pelvis and back up to the top of the colon
lesser omentum
smaller fold of mensentery that extends between the liver, sup. suface of the stomach and a portion of the deodenum
