An individual eats a hamburger. Which two systems must interact to transfer the nutrients in the hamburger to human muscle tissue?

Digestive and circulatory

Explanation:

The digestive system includes a set of organs that together breakdown the complex nutrients present in the food we eat into simpler substances. The proteins, carbohydrates and other nutrients present in a hamburger are digested by the digestive enzymes secreted by various organs of the digestive system.

Digestion of nutrients completes in the small intestine of the digestive system. The digestion products of the hamburger are then absorbed through the cells of the wall of the small intestine. The absorbed nutrients enter the circulatory system and are carried to various body cells such as muscle cells via the blood.
