1
Q

Body cavities

A

Spaces located within the body that help to protect, seperate and support internal organs
Separated by bones, muscles and/or ligaments

2
Q

Thoracic Cavitiy

A

Encircled by the ribs, muscles of the chest, sternum and the thoracic portion of the vertebral column

3
Q

Cavities in the thoracic cavity

A

Pericardial
Pleural
Mediastinum

4
Q

Pericardial Cavity

A

A fluid filled space that contains the heart

5
Q

Pleural Cavities

A

Two fluid filled cavities on either side of the thoracic cavity each containing a lung

6
Q

Mediastinum

A

Central position of the thoracic cavity, lies between lungs, extends from the ribs(front) to vertebral column (back) and occupies space from the first rib (top) to the diaphragm (bottom)

7
Q

Abdominopelvic cavity

A

Extends from the diaphragm (top) to the groin(bottom)

Surrounded by the abdominal wall and the bones and muscles of the pelvic

8
Q

Cavities in Abdominopelvic cavity

A

Abdominal

Pelvic

9
Q

Abdominal cavity

A

Located inferior to the diaphragm and superior to the pelvic cavity
Contains stomach, spleen, liver, gallbladder, small intestines and most of the large intestine

10
Q

Viscera

A

All organs located within both the thoracic and abdominopelvic cavities

11
Q

Serous Membranes

A

Thin, slippery, double layered membranes that cover the viscera of the thoracic and abdominal cavities

12
Q

Parts of serous membranes

A

Parietal layer
Visceral layer
Serous fluid

13
Q

Parietal layer

A

Lines wall of cavity (outside)

14
Q

Visceral layer

A

Attaches to outside of organs within the cavity (inside)

15
Q

Serous fluid

A

Reduces the friction between the two layers allowing the viscera to slide around to some degree during body movement

16
Q

Peritoneum

A

The serous membrane within the abdominal cavity

17
Q

Retroperitoneum

A

Most abdominal organs are enclosed by the peritoneum however some other organs are located between the peritoneum and the posterior portion of the abdominal wall

18
Q

Retroperitoneum organs

A

Kidneys, adrenal glands and pancreas
