Cortisol is produced and secreted by the adrenal glands. Production of the hormone is regulated by the hypothalamus in the brain and by the pituitary gland, a tiny organ located below the brain.

Accommodation. On your Celebrity cruise, luxury comes as standard. We offer a range of rooms (or staterooms as they are called onboard) from cosy inside rooms to sprawling suites. Your private sanctuary at sea is as luxurious as any modern hotel â and many come with sweeping balcony views for you to enjoy.
