Chapter 2: Terms Pertaining to the
Body as a Whole
In this chapter you will
1. Define terms that apply to the
structural organization of the body.
2. Identify the body cavities and
recognize the organs contained within
those cavities.
3. Locate and identify the anatomical and
clinical divisions of the abdomen.
In this chapter you will
4. Become acquainted with terms that
describe positions, directions, and
planes of the body.
4. Identify meanings for new word
elements and use them to understand
new medical terms.
