What is the movement of simple food substances into blood called?
Answer and explanation
Correct answer: Absorption
Digestion breaks complex food into soluble, simple substances such as glucose, amino acids and fatty acids. These products pass through the wall of the small intestine into the blood or lymph; this movement is called absorption. Hence option A is correct. Swallowing only moves food into the alimentary canal, excretion removes wastes, and respiration releases energy rather than transferring digested nutrients into blood.
