the heart, blood and blood vessels

What is the difference between cardiovascular system and circulatory system?
From the hard-working heart, to our thickest arteries, to
capillaries
so thin that they can only be seen through a microscope, the cardiovascular system is our body’s lifeline. The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries.
Is blood part of the cardiovascular system?
The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of
the heart
