Study Notes

Body Cavities and Their Organs

Thoracic Cavity
- Separate from abdominopelvic cavity by the diaphragm.
- Contains the heart, lungs, esophagus, trachea, and thymus gland.
Abdominopelvic Cavity
- Houses essential digestive and excretory organs.
- Includes intestines, liver, spleen, stomach, gallbladder, and kidneys.

Dorsal and Ventral Cavities

Dorsal Cavity
- Main body cavity with two divisions: spinal cavity and cranial cavity.
- Spinal cavity contains the spinal cord.
- Cranial cavity houses the brain.
Ventral Cavity
- Main body cavity divided into thoracic and abdominopelvic cavities.
- Further subdivisions:
  - Thoracic Cavity: Contains pleural and pericardial cavities.
    - Pleural cavity contains the lungs.
    - Pericardial cavity surrounds the heart.
  - Abdominopelvic Cavity: Further divided into abdominal and pelvic cavities.
    - Abdominal cavity contains stomach, liver, intestines, spleen, gallbladder, and kidneys.
    - Pelvic cavity holds terminal portion of large intestine, urinary bladder, and reproductive organs (uterus).

Specific Cavities and Structures

Pelvic Cavity
- A subsection of the abdominopelvic cavity, enclosed by hip bones.
- Includes the terminal portion of the large intestine, urinary bladder, and reproductive organs (uterus).
Abdominal Cavity
- Portion of the abdominopelvic cavity.
- Comprises stomach, liver, intestines, spleen, gallbladder, and kidneys.
Mediastinum
- Divides thoracic cavity into two compartments for the right and left lungs.
Pleural Cavity
- A thin fluid-filled space between the visceral and parietal pleura of each lung.
Pericardial Cavity
- A double-walled sac that encases the heart and the roots of great vessels.
