The most obvious answer would be the Circulatory system; however, the Lymph system also transports material throughout the body, it could be compared to the sewer system in a city. If this is for homework though, the right answer would most assuredly be Circulatory system.
The nervous system, which controls the endocrine glands, telling them when to release hormones The circulatory system, which transports the hormones to target cells You could also include the urinary system; whilst the kidneys are a part of the endocrine system, their other role is to excrete water & salts - the levels of both of which help to maintain homeostasis
Circulatory

probably your veins
The digestive system and the cardiovascular system via the blood vessels. The nervous system is the administrator which decides where the hormones need to go and do their work.
endocrine
well i know the function of it but not what you want i will still give you the function: Circulatory System transports oxygen, carbon dioxide, nutrients, waste products, immune components, and hormones. Major organs include the heart, capillaries, arteries, and veins. The lymphatic system also transports excess fluids to and from circulatory system and transports fat to the heart.
The endocrine system controls the body by means of chemical molecules called hormones.
The plasma component of the blood, contained within the cardiovascular system, transports hormones and nutrients.
endocrine glands.
