The phenomenon of biochemical processes' serving to regulate distant tissues by means of secretions directly into the circulatory system is called endocrine signaling. The major endocrine glands include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, and adrenal glands. The endocrine system is in contrast to the exocrine system, which secretes its hormones to the outside of the body using ducts. The endocrine system is an information signal system like the nervous system, yet its effects and mechanism are classifiably different. The endocrine system's effects are slow to initiate, and prolonged in their response, lasting from a few hours up to weeks. The nervous system sends information very quickly, and responses are generally short lived. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. The field of study dealing with the endocrine system and its disorders is endocrinology, a branch of internal medicine. Special features of endocrine glands are, in general, their ductless nature, their vascularity, and commonly the presence of intracellular vacuoles or granules that store their hormones. In contrast, exocrine glands, such as salivary glands, sweat glands, and glands within the gastrointestinal tract, tend to be much less vascular and have ducts or a hollow lumen.

It was once home to Cuddles, a male orca, or killer whale. He was housed at the zoo from 1971, until his death in February 1974. The dolphin and whale pools were modified seal and sea lions pools with the walls being built up to create more depth. However, these plans fell foul of the local planning laws and the zoo was ordered to return the pools to the original state. As the zoo was not prepared to invest in new purpose built pools the whale Cuddles was put up for sale, but died before being moved, from long-term gastro-intestinal problems. The pools were returned to their original design and now house sea lions.
