The circulatory system relies on the respiratory system to provide oxygen to the blood and remove carbon dioxide. It also depends on the digestive system to provide nutrients and energy for the body to function properly.

Instead, it consists of a fluid-filled body cavity called pseudocoelom that helps transport nutrients and waste throughout their body. This system relies on the movement and contraction of muscles to circulate fluids.
