Exocrine glands are glands that excrete contents via a duct. Notable examples would include sweat glands, salivary glands etc - Interestingly, the liver would also be included in this definition, as it excretes via ducts.
When you ask which is
its definitely liver
Liver and then pancreas, yes.
Skin by itself is not an exocrine gland: sweat and sebaceus glands are rather small. Stomach, small and large intestine probably contain most exocrine glands...
