The circulatory system and the heart work together to maintain blood pressure within a normal range of values
Brain (neural), lungs (i can't remember why but the rhythm of breathing affects the heart rate), and circulatory system (the blood flow, difference in pressure triggers the heart beat).
Circulatory
The heart rate depends on the circulatory system to circulate the blood through the vains and blood vessels. It also depends on the respitory system to breath in oxygen from the lungs, to help the heart pump more blood and give the body a good heart rate pulse... LOL:))
The heart is an organ within the circulatory system. It is make up of different tissues working together to pump blood.
