12. Body Cavities

13. Anterior (Ventral) Posterior (Dorsal)

15. Dorsal Body Cavity 1. Cranial Cavity Contains the brain and CSF. Protects this delicate tissue. 2. Spinal Cavity Contains the spinal cord and CSF. Protects this delicate tissue.

16. Ventral Body Cavity 1. Thoracic Cavity Contains: a) Plural cavities (lungs inside). b) Mediastinum i) Pericardial cavity (heart). 2. Abdominopelvic Cavity Contains: stomach, intestines, gallbladder, liver, spleen, bladder, reproductive organs.

17. B. Pericardium - lines the pericardial cavity. Mediastinum Contains: Heart, thymus, trachea, esophagus, vessels (aorta), nerves. A. Pleura - membrane lining the pleural cavities. Serous Membranes - line ventral body cavities, has 2 portions: Visceral Parietal

18. Peritoneum - lines the peritoneal cavity (this is inside the abdominal cavity). The Abdominopelvic cavity contains the Peritoneal cavity Mesenteries - support and stabilize the digestive organs in abdominal cavity.
