What happens if not all the glucose in the ileum is absorbed into the blood? Watch
Say the body only relied on facilitated diffusion to transport glucose from the ileum to the bloodstream. Eventually, an equilibrium would be established and there would be equal concentrations of glucose on either side of the intestinal epithelium and so not all of the glucose in the body could be absorbed into the blood. What would happen to the glucose left over in the kidney? And how would this effect glucose reabsorption?
