Body cavities and their Contents

There are 4 main body cavities, these are:

Head

The head consists of:

Thorax

The chest or thoracic cavity contains:

These organs are protected by the thoracic cage, and this is formed by the thoracic vertebrae, the ribs, the costal cartilages, and the sternum

Abdomen 

The abdomen contains:

Pelvis

The pelvis contains:

Planes of the Body

Although the planes of the body are not generally used in the pre-hospital environment I thought I'd add them as they come under the same heading of anatomical directional terms.
