How do the digestive and circulatory systems deliver food to cells?

Digestive system

The digestive system breaks down food into molecules that the body can absorb and use for energy. The process of digestion begins in the mouth, where food is chewed and broken down by saliva. The food then travels to the stomach, where it is further broken down by gastric juices. The stomach then churns the food and passes it to the small intestine, where nutrients are absorbed.

Circulatory system

The circulatory system transports nutrients, oxygen, and hormones to cells throughout the body. The heart pumps blood through a network of blood vessels, which deliver blood to cells. The blood delivers oxygen and nutrients, which cells need for energy and growth. The blood also removes waste products, which are then excreted from the body.

How the two systems work together

The digestive system and the circulatory system work together to deliver food to cells. The digestive system breaks down food into molecules that the body can absorb. The circulatory system then transports these molecules to cells throughout the body, where they are used for energy and growth.
