9-2. BASIC COMPONENTS OF ANY CIRCULATORY SYSTEM

The four basic components of any circulatory system are a vehicle, conduits, a motive force, and exchange areas.

a. Vehicle. The vehicle is the substance which actually carries the materials being transported.

b. Conduits. A conduit is a channel, pipe, or tube through which a vehicle travels.

c. Motive Force. If we say that a force is motive, we mean that it produces movement. Systems providing a motive force are often known as pumps.

d. Exchange Areas. Since the materials being transported must eventually be exchanged with a part of the body, special areas are developed for this purpose. They are called exchange areas.
