Study Notes
Body Cavities Overview
- Abdominal cavity houses digestive organs: intestines, stomach, liver.
- Pelvic cavity contains bladder, reproductive organs, and rectum.
- Body is partitioned into superior thoracic cavity and inferior abdominopelvic cavity.
Body Cavities and Membranes
- Posterior aspect differs from ventral cavity; ventral subdivisions lined with serous membranes.
- Two layers of serous membranes exist:
- Parietal Layer: Lines internal body wall, does not move with the organs.
- Visceral Layer: Covers organs, moves with them, directly attached.
Serous Cavity and Fluid
- Serous cavity is the space between parietal and visceral layers.
- Serous fluid acts as a lubricant, reducing friction from organ movement against the body wall.
Thoracic Cavity Details
- Mediastinum is the central space within the thoracic cavity, containing heart, thymus, esophagus, trachea, and major blood vessels.
- Pericardium (heart protection) has two layers:
- Parietal Pericardium: Outer layer forms the heart's sac.
- Visceral Pericardium: Covers heart's external surface.
- Pericardial Cavity: Space containing serous fluid between the layers.
Pleural Membranes
- Pleura associated with lungs consists of:
- Parietal Pleura: Lines the interior of the thoracic wall.
- Visceral Pleura: Covers the lungs' external surface.
- Pleural Cavity: Space containing serous fluid between the layers.
Abdominopelvic Cavity Structure
- Abdominal Cavity: Superior area housing most digestive organs, kidneys, and ureters.
- Pelvic Cavity: Inferior area between hip bones containing the lower large intestine, remaining ureters, urinary bladder, and internal reproductive organs.
- Peritoneum (lining for abdominopelvic cavity):
- Parietal Peritoneum: Outer layer lining internal walls.
- Visceral Peritoneum: Covers most abdominal and pelvic organs.
- Peritoneal Cavity: Potential space with serous fluid between layers.
Importance of Serous Membranes
- Serous membranes prevent friction and excess heat due to organ movement, essential for organ function.
- The dual-layered structure offers protection and lubrication, ensuring organs can move without damaging surrounding tissues.
