Endocrine System 2

The endocrine system is made up of specialized organs called glands. The glands in the endocrine system are specialized in that they have no ducts. Glands which have ducts release their secretions into ducts, whereas glands without ducts release their secretions into the blood. The main endocrine glands are: adrenal, pituitary, thyroid, ovaries and testes. [CG] {NR}
