B
After absorption, the bloodstream carries nutrients to the liver because it has so many important metabolic functions in the body and so its nutrient needs take priority. Hormones that regulate blood glucose level are produced by the islets of Langerhans in the pancreas. The liver stores some substances and eliminates others, but this is not the primary reason that blood travels there directly from the intestines. The functions of the liver are very different from those of the sto-mach.
