Pituitary
(From archive.cnx.org)

The posterior lobe does not produce hormones itself, but it stores hormones synthesized by the hypothalamus and secretes them into the blood stream as needed

Antidiuretic hormone, ADH (vasopressin)

The two primary functions of ADH are to retain water in the body and to constrict blood vessels.

Oxytocin

The two main actions of oxytocin are contraction of the uterus during childbirth and stimulating the production of breast milk.
