No. The digestive system is strictly for eating and disposing that food. There is no blood in your stomach (or at least, there is not supposed to be), but there are blood vessels that go around the organs in your digestive system. However, the blood does not go through them.
According to almost all researches, exercise is very good for your digestive system since it makes your body move and not just be inactive. People need to eat healthy with at least 40 gms of fiber a day in order to maintain a healthy digestive system.
here are some systems I know one is a digestive system also a organ system a respiratory and circulatory system there are also nervous system and last but not least musculoskeletal system
If you mean what do the two systems do, then I can answer your question.The Digestive System allows you to digest, or break down the food you eat. The Digestive System contains your mouth, esophagus, stomach(the most obvious one), small intestine, and the large intestine. The process of Digestion is into your mouth down into your esophagus into your stomach through your small intestine, then your large intestine. I hope you found that at least a little imformative! Cuz I'm not good at explaining that kinda stuff. lol
