Study Notes
Ventral Body Cavity
- Located in the anterior part of the body and is the larger of the closed body cavities.
- Houses internal organs known collectively as the viscera.
Major Subdivisions
- Thoracic Cavity:
- Enclosed by the ribs and chest muscles.
- Acts as a protective compartment for vital organs.
Further Subdivisions of the Thoracic Cavity
-
Pleural Cavities:
- Comprise two fluid-filled spaces, each surrounding one lung.
- Help reduce friction during respiratory movements.
-
Pericardial Cavity:
- A fluid-filled space surrounding the heart.
- Facilitates heart movement and minimizes friction during cardiac cycles.
