Study Notes
Body Cavities Overview
- Body cavities are spaces within the body that house and protect internal organs.
- They are divided into various categories based on location and function.
Cranial Cavity
- Encloses and protects the brain.
- Located within the skull.
Thoracic Cavity
- Houses organs within the chest, including the heart and lungs.
- Separated from the abdominal cavity by the diaphragm.
Ventral Cavity
- Consists of the thoracic and abdominopelvic cavities.
- Positioned at the front (ventral) part of the body.
Diaphragm
- A muscular wall separating the thoracic cavity from the abdominopelvic cavity.
- Plays a vital role in respiration by contracting and expanding the lungs.
Abdominopelvic Cavity
- Combination of the abdominal and pelvic cavities.
- Contains organs related to digestion, reproduction, and excretion.
Abdominal Cavity
- Encloses organs such as the stomach, liver, and intestines.
- Located superiorly in the abdominopelvic cavity.
Pelvic Cavity
- Contains the urinary bladder, reproductive organs, and rectum.
- Located inferiorly in the abdominopelvic cavity.
Vertebral Canal
- A passageway formed by the vertebral column.
- Houses the spinal cord and nerve roots.
Dorsal Cavity
- Comprised of the cranial and vertebral cavities.
- Located at the back (dorsal) side of the body.
Pericardial Cavity
- The space surrounding the heart.
- Part of the thoracic cavity, provides protection and allows heart movement.
Pleural Cavity
- Contains the pleural fluid and exists between the layers surrounding the lungs.
- Provides lubrication and reduces friction during breathing.
