the digestive system is responsible for breaking down food into usable nutrients for the body, which other organ system works with the digestive system to transport nutrients to all the muscles, organs, and cells in the body?

Circulatory System

Explanation:

As soon as 5he digestive system has broken down the foods to their smallest unit, the circulatory system helps to move the nutrient to where they are needed.

Blood is a medium of transport in higher vertebrates and is being pumped by the heart and flows through network of capillaries. Blood also transport oxygen that helps in the breakdown of carbohydrates to produce energy and get rid of waste such as carbondioxide through the excretory system.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
