Detailed explanation-1: -The stomach and small intestines absorb the glucose and then release it into the bloodstream.

Detailed explanation-2: -Glucose travels from the intestinal lumen into the intestinal epithelial cells through active transport, and then glucose enters red blood cells through facilitated diffusion. GLUT-1 is one of the major glucose transporters for red blood cells.
