Cardiovascular System I: The Beating Heart


The cardiovascular system is a key element in transporting and exchanging substances (such as nutrients, wastes, oxygen, and carbon dioxide) between the environment and the cells that function in tissues. Cardio is from the Greek word kardia, meaning heart, and vascular is from the Latin word vasculum, meaning vessel.

In Part I, we look at the operation of the mammalian heart, using the human heart as an example. It is the heart that provides the motive force to move blood through the circulatory system so that metabolic fuels and waste products can be transported to and from the body tissues.

In Part II, we look at the vascular system and the exchange of substances between blood and body tissues via the capillaries.
