these studies indicate that pancreatic proteins are removed from the blood circulation by at least three separate pathways : ( a ) uptake and degradation by a variety of tissues in the body ( approximately 97 % of injected radioactivity ) , ( b ) excretion of intact proteins into urine ( 1 % -2 % ) , and ( c ) transport of intact proteins into bile ( 0.3 % -0.5 % ) .
