In this module, you explored circulation. Like a water treatment plant, the mechanics of a circulatory system include pumps, valves, tubing, and fluids. The primary structures of the circulatory system are the heart, veins, arteries, capillaries, and blood.

Blood moves through the body transporting nutrients and waste. Cellular components of blood protect the body from invading pathogens and from blood loss. 

Blood is a multi-faceted component of your circulatory system that transports nutrients, gases, and wastes, contains cells for immunity, and has the ability to clot if the body is injured. Energy flow is also maintained via the circulatory system. The ability for blood to absorb heat and the design of the network of blood vessels allows heat to be transferred or conserved in order to maintain body temperature. Blood pressure is a mechanism to control the exchange of matter and a measure of overall health.
