Body Cavities and Membranes

 

Know pg 34 in your Anatomy/physiology book fourth edition

 

The body is divided into 2 major body cavities

 

Serous membranes- 2 layers, with a space in-between filled with serous fluid=cavity

 

Visceral

 

Parietal

 

Ex: parietal pleura

 

Pleural cavity

 

Visceral pleura

 

Peritoneum

 

Messentaries

 

Retroperitoneal

 

The body is made up of 60-70% water- 2/3 of all the fluid is found in Intracellular fluid

 

Intracellular (ICF) 2/3 fluid in the cell

 

Extracellular (ECF) 1/3 any fluid outside of the cell
