Question 1 of 5
In a human, the movement of glucose from the digestive tract to muscle cells is most directly a result of
Correct Answer: B
Rationale: Glucose moves from the digestive tract to muscle cells via absorption (uptake into blood) and circulation (transport via bloodstream). Ingestion and digestion prepare glucose but don't move it. Anaerobic respiration uses glucose, not transports it. Protein synthesis is unrelated.
Question 2 of 5
The digestive system processes food into usable and unusable materials. The usable materials are sent to the body's cells as food. What happens to unusable materials?
Correct Answer: C
Rationale: Unusable materials (waste) move to the large intestine for water absorption and eventual disposal as feces, making C correct. The pancreas produces enzymes, the right ventricle is heart-related, and the small intestine absorbs nutrients, not stores waste.
Question 3 of 5
Structures of the small intestine that aid in the absorption of nutrients include
