Study Notes

Major Body Cavities

Two major body cavities: Dorsal and Ventral.

Dorsal Cavity

Subdivisions include Cranial Cavity and Vertebral Cavity.
Dorsal cavity houses the brain and spinal cord.

Ventral Cavity

Located anteriorly, it houses internal organs referred to as "guts" or viscera.
Divided into two subdivisions: Thoracic Cavity and Abdominopelvic Cavity.

Thoracic Cavity

Contains the pleural, mediastinum, and pericardial cavities.
Pleural Cavities are right and left compartments that house the lungs.
Mediastinum is the space between the pleural cavities, containing the thymus, lymph vessels, esophagus, trachea, and nerves.
Pericardial Cavity houses the heart.

Abdominopelvic Cavity

Encompasses both the abdominal cavity and the pelvic cavity.
Abdominal Cavity contains digestive organs.
Pelvic Cavity contains the bladder, reproductive organs, and rectum.

Visceral Organs

All organs are lined with serous membranes except for the brain and spinal cord.

Serous Membranes and Fluid

Serous fluid is the watery, lubricating fluid located between the parietal and visceral layers.
Visceral pleura covers the lungs.
Pericardium lines the pericardial cavity.
Peritoneum lines the abdominal cavity.

Retroperitoneal Organs

Includes the urinary and reproductive organs, located outside of the peritoneal cavity.
