The heart
, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen.
What three main parts make up the circulatory cardiovascular system?

What part of the body is vascular?
The vascular system, also called the circulatory system, is made up of
the vessels that carry blood and lymph through the body
. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.
How does the immune system work with the circulatory system?
