  12. Body Cavities- Portions Axial Portion vs. Appendicular Portion Head Neck Trunk Upper and Lower Limbs

  13. Body Cavities of the Axial Portion Cranial cavity Vertebral canal Thoracic cavity Diaphragm Abdominal cavity Abdominopelvic cavity Pelvic cavity (a) Cranial cavity Vertebral canal Mediastinum Right pleural cavity Thoracic cavity Left pleural cavity Thoracic cavity Pericardial cavity Diaphragm Abdominal cavity Abdominopelvic cavity Pelvic cavity (b)

  14. Serous Membranes • double membrane lining abdominopelviccavity (peritoneum), lungs (pleura), and surrounding the heart (pericardium) • Parietal layer - attaches to cavity wall • Visceral layer - attaches to organ • Serous fluid between layers acts as lubricant

  15. Pleural Membranes = Thoracic/Lungs

  16. Pericardial Membranes= Heart

  17. Thoracic Cavity: Pleural & Pericardial Membranes Plane of section Vertebra Spinal cord Mediastinum Azygos v. Aorta Left lung Esophagus Right lung Rib Right atrium of heart Left ventricle of heart Right ventricle of heart Visceral pleura Visceral pericardium Pleural cavity Pericardial cavity Anterior Parietal pleura Parietal pericardium Sternum Fibrous pericardium

  18. Peritoneal Membranes= Abdomen & Pelvis

  19. Abdominopelvic Cavity: Peritoneal Membranes Spinal cord Plane of section Vertebra Right kidney Left kidney Aorta Inferior vena cava Spleen Pancreas Small intestine Large intestine Large intestine Liver Rib Gallbladder Duodenum Costal cartilage Visceral peritoneum Stomach Peritoneal cavity Anterior Parietal peritoneum

  20. Organ Systems
