Does the cardiovascular system rely on any other systems in the body to function?
Yes. It relies on the nervous system to regulate its rate, the endorcrine system to control a) what it’s built of b) repair. it relies on whatever system the kidneys are to clean it, it relies on the digestive system to give it the sugars it needs to give it the energy it needs. It relies on the hydrodynamic system (external of the body) to recycle water and oxygen.
