Absorption. Digested food molecules are absorbed in the small intestine. This means that they pass through the wall of the small intestine and into our bloodstream. Once in the bloodstream, the digested food molecules are carried around the body to where they are needed.
In the digestive system, absorption means the uptake of digested food into the blood.   Diffusion is one way in which food can be absorbed into the blood. If the conc â¦ entration of food is higher in the intestine than it is in the blood, food can diffuse down the concentration gradient into the blood.   If the concentration of food is lower in the digestive system than in the blood then it cannot be absorbed by diffusion.
