Outline the enteropancreatic circulation of zinc from absorption to utilization and excretion
?Zinc is absorbed in the intestines and can be retained in the intestinal cells by metallothionein. When the body requires zinc, the metallothionein releases the zinc, which binds to albumin for transport throughout the body. Zinc largely ends up in the pancreas to make digestive enzymes, which are then returned to the intestines during digestion, and the zinc is then reabsorbed for reuse. When the body does not require zinc, zinc absorption decreases, and zinc is shed from the intestinal cells for excretion.
