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.

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 cavityThe space inside the teeth and gums that is filled by the tongue when the mouth is closed and relaxed. Synonym: buccal cavitypelvic cavityThe 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: pelvispericardial cavityThe potential space between the epicardium (visceral pericardium) and the parietal pericardium. See: pericardia friction rub; pericarditisperitoneal cavityThe 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 cavityThe potential space between the parietal pleura that lines the thoracic cavity and the visceral pleura that covers the lungs.
