Body Cavities: Dorsal and ventral
Dorsal sub divided into cranial and spinal cavities. Cranial cavity is formed by the skull, it contains and protects the brain.
The spinal cavity, also known as vertebral canal, protects the spinal cord in a bony cavity created by the vertebra.
Thoracic
Thoracic cavity is part of the ventral (The ventral cavity is a large cavity in the front of the human body that contains many vital organs. It’s made up of the thoracic cavity, the abdominal cavity, and the pelvic cavity)
Pleural Cavities
Each contain a lung
Pericardial Cavity
Contains the heart and is medial to the pleural cavities, the middle or inner part of a structure or body part
Mediastinum Cavity
Contains the esophagus, trachea, thymus, gland, aorta and inferior vena cave (A large vein that carries blood to the heart from other areas of the body)
Ventral membrane
These membranes line the coelomic (The coelom is located between the body wall and the digestive tract.)
cavities of the body, and they cover the organs located within those cavities. They are essentially membranous bags, with mesothelium lining the inside and connective tissue on the outside.
Abdominal cavity
consists of the stomach, duodenum (first part), jejunum, ileum, liver, gallbladder, the tail of the pancreas, small intestine and colon. This cavity is bound by the diaphragm, the body wall, and the pelvic cavity.
Pelvic cavity
Holds the urinary bladder, ureters, urethra, lower part of the large intestine and small intestine. It also houses the female reproductive organs and some male organs. This cavity is inferior to the abdominal cavity.
Right upper quadrant RUQ
Contains a majority of the liver, gallbladder, portion of pancreas, right kidney, plus portion of small intestines and colon.
Left upper quadrant LUQ
Contains a portion of the liver, stomach, spleen, majority of the pancreas, left kidney and portion of small intestines and colon.
Right lower quadrant RLQ
Contains half of the small intestines and colon, right ovary and fallopian, appendix and the right ureter.
Left lower quadrant LLQ
Contains half the small intestines and colon, left ovary and fallopian tube and left ureter.
