It produces hormones that simulate the production of certain infection fighting cells.4.The thyroid produces a hormone (thyroxin) (under control of the pituitary gland) that controls your rate of metabolism.5.The parathyroid controls the body's calcium level.6.The adrenal produces epinephrine(adrenaline) and norepinephrine(nerotransmeter for hormones) in order to maintain susceptible blood sugar levels
