Unformatted text preview: Anatomy Lab #8 Abdominopelvic Organs: The Digestive and Urogenital Systems 1 he Digestive System he abdominopelvic cavity extends from the diaphragm to the floor of the pelvis and contains two divisions. The larger and upper division is the abdominal cavity. This cavity is bound by the abdominal wall and the lumbar vertebrae. The smaller and lower division is the pelvic cavity, which houses the organs of the urinary and reproductive systems and is bound by the bones of the pelvis and sacrum.

It is lined by ucous membrane, some of which is specialized to produce saliva. However, most saliva is produced by the three pairs of salivary glands (parotid, submandibular, and sublingual) that are connected to the oral cavity by exocrine ducts. Food or drink are pushed into the oropharynx by the tongue. By elevating the hyoid, the epiglottis is closed over the opening to the larynx, and food or drink are pushed through the laryngopharynx and into the esophagus where peristaltic contractions propel it to the stomach.

The pelvic viscera will be discussed later....
