The major body cavities include the ____________________ cavity, which houses the brain, the ____________________ cavity for the heart and lungs, the ____________________ cavity, mainly for the digestive organs, and finally the __________________ cavity, for the reproductive organs. 3. Label the cavities on Figure E. 1 3 2 7 4 5 6 FIGURE E Who Am I? 4. I am the cavity that contains the brain and spinal cord. ____________________ 5. I am the cavity that contains the thoracic and abdominopelvic cavities. ____________________ 6. Label the and what part of the body it contains. Match the organs with what cavity they are in.

The outer part of the membrane that lines the cavity is the ____________________________ membrane 2. The part that covers the organs is the ____________________________ membrane. 3. ________________________________– lines thoracic or chest cavity and protects the lungs 4. ________________________________– lines the heart cavity and protects the heart 5. ________________________________– lines the abdominal cavity and protects abdominal organs 19.
