Study Notes
Body Cavities
What are Body Cavities?
- Regions within the body that contain internal organs
- Protected by bones, muscles, and membranes
Types of Body Cavities
-
Dorsal Body Cavity
- Located in the upper back region
- Contains the cranial cavity (brain) and spinal cavity (spinal cord)
-
Ventral Body Cavity
- Located in the chest and abdominal regions
- Divided into two parts:
-
Thoracic Cavity (chest region)
- Contains the lungs, heart, and major blood vessels
-
Abdominopelvic Cavity (abdominal region)
- Contains the digestive organs, kidneys, and reproductive organs
-
Thoracic Cavity (chest region)
Functions of Body Cavities
- Protect internal organs
- Support and cushion organs
- Allow for organ movement and expansion (e.g., lungs, heart)
- Provide a pathway for nerves and blood vessels
Membranes Associated with Body Cavities
- Meninges: surround the central nervous system (brain and spinal cord)
- Pleura: surround the lungs
- Peritoneum: lines the abdominopelvic cavity and covers abdominal organs
- Pericardium: surrounds the heart
