digestive system -> circulatory system -> body cells circulatory system -> body cells -> digestive system digestive system -> body cells -> circulatory system circulatory system -> digestive system -> body cells
I gave my students this multiple choice question: Which pathway do most nutrients take after a person takes a bite of food?

Only one answer is correct among these 4 choices:
- digestive system -> circulatory system -> body cells
- circulatory system -> body cells -> digestive system
- digestive system -> body cells -> circulatory system
- circulatory system -> digestive system -> body cells

Could you tell me which one is correct?
