Exocrine glands release products through tube like structures called ducts. Sweat, tears and digestive juices are released through exocrine glands. Endocrine glands release products (hormones) directly into the bloodstream. A few of the glands include: Gland Functions Hormones Released Hypothalamus Control pituitary gland Produces small amounts of hormones to regulate pituitary gland Pituitary gland Produces 9 hormones that regulate body function and other glands GH (growth hormone), FSH (stimulates production of egg and sperm), LH (prepares uterus for implantation of egg, ADH (water reabsorption by kidneys), oxytocin (childbirth) Adrenal glands Release hormones that help the body deal with stress and kidney function Epinephrine, norephinephrine, which
