The digestive system is the process that enables us to physically break down the essential nutrients and liquids in food from an external environment into our internal environment. Through the physical and chemical processes in the digestive and gastrointestinal tract, the circulatory and digestive systems play an integral part of this process which is essentially for our body's energy and growth. The circulatory system absorbs, transports and distributes the broken down nutrients to our tissues and cells. And without the digestive process our tissues and cells would not receive the essential material that enables us to move, grow AND live. So the digestive needs the circulatory system and vice versa.
If you mean "absorption" when you say "circulation", digestion is necessary because the body cannot absorb the nutrients directly from food. The nutrients are "locked" inside. Digestion breaks food apart so that nutrients can be more easily accessed and absorbed.
The circulation system gives oxygen to the digestive system organs to keep them alive and carries nutrients from the digestive system to every cell in the body.
Circulation to the digestive system increases to help the body digest food.
