It is lined with a serous membrane, the peritoneum, and contains the following organs: stomach with the lower portion of the esophagus, small and large intestines (except sigmoid colon and rectum), liver, gallbladder, spleen, pancreas, adrenal glands, kidneys, and ureters. It is continuous with the pelvic cavity; the two constitute the abdominopelvic cavity. See: abdomen; abdominal quadrants for illus.

1. Any hollow space within the body. See: illustration
2. A hidden body space that is accessible from the outside, e.g., rectum or vagina. Referred to in “body cavity search for contraband”.

glenoid cavity
Glenoid fossa (2).joint cavity
The articular cavity or space enclosed by the synovial membrane and articular cartilages. It contains synovial fluid. Synonym: joint space
laryngeal cavity
The hollow inside the larynx from its inlet at the laryngopharynx to the beginning of the trachea. It has three segments (from top to bottom): vestibule of the larynx, ventricle of the larynx, infraglottic cavity.
lesser peritoneal cavity
Omental bursa.medullary cavity
The marrow-filled space in a bone.
nasal cavity
One of two cavities between the floor of the cranium and the roof of the mouth, opening to the nose anteriorly and the nasopharynx posteriorly. Its lining of ciliated epithelium warms and moistens inhaled air, and traps dust and pathogens on mucus that are then swept toward the pharynx. The nasal septum (ethmoid and vomer) separates the nasal cavities, and the olfactory receptors are in the upper part of each cavity. The paranasal sinuses (frontal, maxillary, sphenoidal, and ethmoidal) open into the meatus below the conchae. The orifices of the frontal, anterior ethmoidal, and maxillary sinuses are in the middle meatus. The orifices of the posterior ethmoidal and sphenoidal sinuses are in the superior meatus. The nasal mucosa is highly vascular; blood is supplied by the maxillary arteries from the external carotid arteries and by the ethmoidal arteries from the internal carotid arteries.
oral cavity
The space inside the teeth and gums that is filled by the tongue when the mouth is closed and relaxed.
Synonym: buccal cavitypelvic cavity
The bony hollow formed by the innominate bones, the sacrum, and the coccyx. The major pelvic cavity lies between the iliac fossae and above the iliopectineal lines. The minor pelvic cavity lies below the iliopectineal lines. See: pelvis
pericardial cavity
The potential space between the epicardium (visceral pericardium) and the parietal pericardium.
See: pericardia friction rub; pericarditisperitoneal cavity
The potential space between the parietal peritoneum, which lines the abdominal wall, and the visceral peritoneum, which forms the surface layer of the visceral organs. It contains serous fluid.
pleural cavity
The potential space between the parietal pleura that lines the thoracic cavity and the visceral pleura that covers the lungs. It contains serous fluid that prevents friction.
pleuroperitoneal cavity

THORACIC CAVITY
thoracic cavity
The part of the ventral cavity above the diaphragm, the domed muscle that separates it from the abdominal cavity; it is enclosed by the chest wall. The thoracic viscera include the pleural membranes that surround the lungs, the mediastinum between the lungs, which contains the heart and pericardial membranes, the thoracic aorta, pulmonary artery and veins, vena cavae, thymus gland, lymph nodes, trachea, bronchi, esophagus, and thoracic duct. See: illustration
