As it turns out, it is difficult to give a simple answer to this as both are extremely complicated. However, one way to think of it is that you can't have one without the other, and expect to survive. The nervous system of course needs nutrients to be brought to it and waste molecules to be taken away, this is accomplished by the circulatory system. Interestingly enough, the circulatory system is heavily innervated by the nervous system. Signals from various parts of the nervous system do things like change the heart rate, either faster or slower, change the constriction or dilation of the blood vessels, which alters the rate of flow for the circulatory system, and uses the circulatory system to dissipate heat if the body and the brain senses that it is too warm.
The circulatory system carries O2 & nutrients to most parts of the body & removes waste products. The center of this system is the heart. The heart rate is controlled by signals from the nervous system (if you want more specificity, Wikipedia will oblige). If the flight or fight response is in effect, or under athletic duress, the heart is recieving signals to pump quickly; under conditions of rest, the heart rate is modulated to a lower, energy conserving, resting state. (Ditto for the rate of respiration)
The nervous system regulates the heart beat.

the nervous system and the circulatory system
The circulatory, endocrine, muscular, and nervous systems help rid the body of wastes via the kidneys. The muscular and nervous systems help rid the body of solid wastes via the rectum. The nervous and circulatory systems help rid the body of wastes via the skin. The circulatory, skeletal, nervous, and muscular systems help the respiratory system rid the body of gaseous wastes.

Mammals have nervous, digestive, circulatory, skeletal, immune, muscular, integumentary, and excretory systems.
