Study Notes
Ventral Body Cavity
- Comprises the thoracic cavity and the abdominopelvic cavity, housing vital organs.
Thoracic Cavity
- Divided into three sections: two pleural cavities and the mediastinum.
- Encloses essential organs such as the heart and lungs.
Pleural Cavities
- Two chambers, each specifically containing a lung, allowing for respiratory function.
Mediastinum
- Central compartment within the thoracic cavity.
- Houses the pericardial cavity, which contains the heart, and the superior mediastinum.
Pericardial Cavity
- Located within the mediastinum, this cavity encases the heart within the pericardial sac.
Superior Mediastinum
- Contains critical structures including the trachea and esophagus, facilitating air and food passage.
Diaphragm
- A muscular membrane that acts as a separator between the thoracic cavity and the abdominopelvic cavity, essential in the breathing process.
Abdominopelvic Cavity
- A composite cavity divided into the abdominal cavity and pelvic cavity, containing various organs.
Abdominal Cavity
- Encloses several important organs, including the liver, stomach, and kidneys, as well as other digestive components.
Peritoneal Cavity
- A fluid-filled space that surrounds many organs located in the abdominopelvic cavity, providing protection and support.
Pelvic Cavity
- Contains the bladder, some reproductive organs, and the rectum, playing a role in excretory and reproductive functions.
