How do nutrients, absorbed by the digestive system, travel to the individual cells of the human body?
A. The nutrients are absorbed from the small intestine into the blood and move through the
circulatory system to the body cells.
B. The nutrients move from the small intestine directly to the liver and then move through the
excretory system to the body cells.
C. The small intestine forces the nutrients into the respiratory system, where the nutrients are
then dissolved in fluids used by the body cells.
D. The body cells send nerve impulses indicating a lack of nutrients to the small intestine, and
the small intestine sends the nutrients back to the cells.
