What organs in your body carry out a similar function as the green glands on a crayfish?

The green tissue in the body cavity of the crayfish, lobster, or crab (called tomalley to connoisseurs) found below and rear of the base of the antennae, performs the same function as the pancreas and liver in humans (or the hepatopancreas in some other arthropods). Some sources say 'kidneys' but because the green organ is ducted into the digestive system (like the bile duct from the liver in humans) and because the gills are the primary excretory site for the higly toxic ammonia they produce as part of their nitrogen metabolism, that position might need further substantiation.
