Question

Nutrients enter the bloodstream during the process of

A) Locomotion
B) Respiration
C)Elimination
D)Absorption

Answer 1

D) Absorption.

Raw materials from the foods we eat are chemically digested so that the complex molecules in food are broken down into simple chemical substances. This allows the substances to be thin enough to pass through the thin walls of the villi - lining of the intestine - and then pass through capillaries and into the bloodstream. Hope this helps.
