What is the difference between a mixed endocrine gland, and a purely endocrine gland? Give an example of each?

Answer 1

An endocrine gland (i.e. adrenal gland) is a ductless gland that produces hormones and a mixed endocrine gland (i.e. pancreas) also has exocrine functions. Which means it has ducts and produces local products that are not hormones. The pancreas also produces digestive enzyme that are not hormones.
