Answer 2

Hey friend.... :-)

Here is your answer

The cardiovascular system does not produce energy, it allows the transport of energy rich substances [like glucose, fatty acids and other nutrients] and oxygen in the blood to the body's cells so they can produce the energy to run those cells.

Cells produce energy through process called cellular respiration.
