Body Cavities

Body Cavity

It is a space that holds and protects your organs

Holds the brain

Cranial cavity

Holds the spinal cord

Vertebral cavity

The cavity that contains three smaller cavities

Thoracic cavity

The cavity that contains your heart and lungs

Thoracic cavity

The three smaller cavities within the Thoracic cavity

Plueral cavity

Pericardial cavity

Mediastinum

Pleural cavity

Situated in your thoracic cavity

Covers and protects your lungs

L and R cavities

Mediastinum

Medial to lungs and extending from sternum to spinal column and from rib 1 to the diaphragm

Contains all thoracic organs, including the heart (inside of the pericardial cavity), except for the lungs

Abdominopelvic cavity

contains both your abdominal cavity and pelvic cavity, which are not separated from one another by any space or wall

separated from the thoracic cavity by the diaphragm

List the Quadrants of the abdominopelvic cavity (1-4 in order)

System used by clinicians to distinguish the site of pain, masses, or abnormalities

Separates the region into 4 parts: Upper Right Quadrant (URQ), Upper Left Quadrant (ULQ), Lower Left Quadrant (LLQ), Lower Right Quadrant (LRQ),

Regions of the abdominopelvic cavity

(LIST 1-9)

Used by anatomists

Separates the cavity into 9 regions:

1. Right Hypochondriac region

2. Epigastric region

3. Left Hypochondriac region

4. Right Lumbar region

5. Umbilical region

6. Left Lumbar region

7. Right Illiac region

8. Hypogastric (pubic) region

9. Left Illiac region

Remember that L and R correspond to the individual's body being studied (not your L and R if you're looking at the person)
