Body Cavities |
- Spaces within the body that help protect, separate, and support internal organs. - Compartmentalize major organs |
|
|
Dorsal Body Cavities |
- 2 continuous cavities (no true separation) - Protects/houses the CNS - Cranial Cavity - Vertebral Canal |
|
|
Cranial Cavity |
- Houses the brain |
|
|
Vertebral/Spinal Canal |
- Houses the Spinal Cord |
|
|
Meninges |
Protective wrappings around organs in the dorsal body cavities and around the CNS |
|
|
Ventral Body Cavities |
- Physically separate - Thoracic Cavity - Abdominopelvic Cavity |
|
|
Diaphragm |
- Organ/muscle that separates the 2 ventral cavities - Sits under the ribcage - Major muscle of breathing, contracts when you inhale |
|
|
Thoracic Cavity |
- Superior - Contains the heart and lungs |
|
|
2 Subcavities of the Thoracic Cavity |
- Pleural Cavities (Lateral) - 2 lungs kept here - Pericardial Cavity (Medial) - Houses the heart - in mediastinum |
|
|
Mediastinum |
- Central region in thoracic cavity directly below the sternum - NOT A CAVITY - Vitalist of vital organs are here |
|
|
Abdominopelvic Cavity |
Largest cavity divided into 2 continuous subcavities: Abdominal and Pelvic |
|
|
Abdominal Cavity |
- Superior Portion - Contains most gut tube organs - Non-gut tube organs: Spleen |
|
|
Spleen |
- Sits behind the stomach - between stomach and kidney - little purple organ - stores WBC |
|
|
Pelvic Cavity |
- Inferior Portion - Tilts Posteriorly - Below brim of pelvis(hips start)→down to crotch - Contain urogenital organs - few digestive organs(distal/sigmoid colon/rectum) |
|
|
Serous Membrane (serosa) |
- Ventral body cavity membrane - covers structures - membrane that secretes a thin serous fluid and they are never exposed to air |
|
|
Serous membrane line with... |
...continuous piece of membrane that lines the walls or organ and cavity wall. |
|
|
Parietal Layer |
Lines wall of cavity |
|
|
Visceral Layer |
Lines wall of organs (inviscerate=cut out internal organs) |
|
|
Parietal/Visceral |
- one piece - only when talking about serous membranes - others are mucous membranes - fluid between two layers |
|
|
Pleura (n.) |
- On walls of lungs/Pleural Cavity (adj.) |
|
|
Pericardium (n.) |
- On walls of heart/pericardial(adj.) cavity |
|
|
Peritoneum (n.) |
- On walls and organs lining in the abdominopelvic(adj.) cavity |
|
|

- Large/Small intestine - Appendix |
|
|
Right Upper Quadrant (RUQ) |

|
|
Right Lower Quadrant (RLQ) |
- Large and small intestine |
|
|
Left Upper Quadrant (LUQ) |
- Stomach - Spleen - Transverse colon |
|
|
Left Lower Quadrant (LLQ) |
- Small Intestine - Sigmoid/Descending Colon |
