A. The endocrine system is made up of the cells, tissues, and organs that secrete hormones into body fluids. The body has two kinds of glands, exocrine (secretes products into ducts) and endocrine (secrete products into body fluids).
The pancreas is both an exocrine and endocrine gland. Its endocrine hormone secretions include insulin and glucagon. Its exocrine secretions consist mainly of digestive enzyme â¦ s such as amylase, lipase, trypsin and chymotrypsin.
