Study Notes

Body Cavities

The human body has two main cavities: dorsal cavity and ventral cavity
Dorsal cavity is divided into cranial cavity and vertebral cavity
Cranial cavity contains the brain, while vertebral cavity contains the spinal cord
Ventral cavity is divided into thoracic cavity, abdominopelvic cavity, and pelvic cavity
Thoracic cavity is further divided into pleural cavity and pericardial cavity
Pleural cavity contains lungs, while pericardial cavity contains the heart
Abdominopelvic cavity is divided into abdominal cavity and pelvic cavity
Abdominal cavity contains digestive organs, while pelvic cavity contains bladder, reproductive organs, and rectum

Serous Membranes

Ventral cavities are lined with serous membranes, which are thin, double-layered membranes
Visceral layer of serous membrane covers organs, while parietal layer lines the wall of the cavity
Serous fluid is produced, which reduces friction as organs move
