Cardiovascular System II: The Vascular Highway


Copyright © Addison Wesley Longman, Inc.

The blood vessels, or vascular system, of the human body form a closed delivery/pickup system that begins and ends with the heart. All the living cells of the body come in contact with blood vessels and, at capillary interfaces, life-sustaining substances move into and out of these microscopic vessels.

In this module, you will overview blood vessel structure and function, circulatory pathways or circuits, exchanges of fluid and solutes at capillaries, and blood pressure as it relates to the vasculature. As this module points out, a crucial aspect of the vascular system is that it connects the body cells with organs of exchange, like the lungs, liver, small intestine, and kidneys.

The purpose of the BioCoach modules is to help you review material you have already studied in class or in your text. Some of the material will extend your knowledge beyond what you have read in your text. You may select a basic concept from the drop-down menu, test yourself in the corresponding Practice, and remedy any problem areas using the more detailed coverage on the corresponding Review page. If you wish, you may skip the Practice and proceed directly to the Review.
