Study Notes
Ventral Body Cavity Overview
- Major divisions: thoracic cavity and abdominopelvic cavity.
- Thoracic cavity includes pleural cavity, pericardial cavity, and mediastinum.
Thoracic Cavity Subdivisions
- Pleural cavity: Surrounds each lung.
- Pericardial cavity: Surrounds the heart.
- Mediastinum: Contains trachea, esophagus, major vessels, and pericardial cavity.
Abdominopelvic Cavity
- Comprised of the abdominal cavity and pelvic cavity.
- Abdominal cavity: Houses digestive organs and glands.
- Pelvic cavity: Contains urinary bladder, reproductive organs, and the last part of the digestive tract.
Functions of the Ventral Body Cavity
- Protects internal organs.
- Facilitates organ movement.
- Linings reduce friction between organs.
Diaphragm Role
- Separates the thoracic cavity from the abdominopelvic cavity.
Serous Membrane Functionality
- Covers organs and cavity walls.
- Composed of two layers:
- Parietal layer: Adheres to cavity walls.
- Visceral layer: Adheres to organs.
- Serous fluid is found between the two layers, reducing friction during organ movement.
Naming of Serous Membranes
- Named based on their anatomical location in the body.
- Pleura: Surrounds lungs (parietal/visceral pleura).
- Pericardium: Surrounds heart (parietal/visceral pericardium).
- Peritoneum: Surrounds viscera in the abdominopelvic cavity (parietal/visceral peritoneum).
