Body Cavities

which cavity's organs are most vulnerable to trauma

abdominal cavity because walls are muscle only, pelvic cavity has pelvic bones

function of serous fluid

allow to slide over each other, no pulling or friction

dorsal body cavity

cranial and vertebral, protects nervous system

pleural cavities

each surround one lung, part of thoracic cavity

viscera

internal organs

serous membrane

membrane of ventral cavity separated from other membranes by serous fluid

parietal pericardium

parietal serosa forming cavity for the heart

parietal peritoneum

parietal serosa on the abdominopelvic cavity wall

parietal pleura

parietal serosa on the walls of a cavity housing a lung

pelvic cavity

part of abdominopelvic cavity, contains urinary bladder, reproductive organs, rectum

cranial cavity

part of dorsal body cavity, encases brain

vertebral cavity

part of dorsal body cavity, encases spinal cord

abdominal cavity

part of the abdominopelvic cavity, contains stomach, intenstines, spleen, and liver

mediastinum

part of thoracic cavity, contains pericardial cavity, surrounds other thoracic organs such as esophagus, trachea, etc.

pericardial cavity

part of thoracic cavity, encloses the heart

diaphragm

separates two subdivisions of ventral body cavity

visceral serosa

serous membrane found on any ventral cavity organ surface

parietal serosa

serous membrane found on any ventral cavity wall

ventral body cavity

thoracic and abdominopelvic, houses internal organs

visceral pleura

visceral serosa on surface of lung

visceral peritoneum

visceral serosa on surface of most abdominopelvic organs

visceral pericardium

visceral serosa on the surface of the heart
