Glands - small organs scattered over various parts of the body. Released during adulthood during physical activities, helps with muscle maintenance and muscle growth. Released from a gland called the pituitary gland.

Act on the small intestine - increases absorption of nutrients. Acts on bronchioles - makes them dilate (become wider) Also works on other organs" blood vessels that are not in use (constriction) Acts on liver - promotes glycogenolysis (breakdown of sugar - availability of energy for muscles during exercise) Acts on adipose tissue - lipolysis (fat breakdown) Sugar in the body is a fuel source - every cell in the body depends on sugar.
