Circulatory System
The Digestive system works with the Circulatory system because the Digestive system makes nutrients to give to the cells. The cells turn it into energy. The body, needs energy, so the Circulatory system is like a delivery system. The Circulatory system meets with the cells and the blood stream dellivars the energy to the other parts of the body.

Skeletal System
The Digestive system needs the food to be grind into tiny mushy piece called pulp, so it is easier to swallow and digest. Also the ribs cover the digestive system’s organs and protect them.

Muscular System
The Digestive system works with the Muscular system when you need to chew your food. Muscles move your jaw bone to chew up the food. Also there are muscles called the sphincter muscles, which lets food into one organ to another. There are two intestinal muscles, that makes the ntestines move the food from the small intestine to the large intestine. There is an other muscle called the esophagus muscle which moves food down the esophagus to the stomach.

Respiratory System
The Digestive system works with the Respiratory system for example, when you gulp too much air and it goes down the esophagus and into your stomach the lungs give air and you burp, so too much air won’t hurt your stomach.
