Hormone.
Chemical messengers.
Through chemical messengers controlled by a negative feedback system.
Neurotransmitter.
The body's chemical communication system that is much slower than the nervous system is called the endocrine system. Both systems are similar because they have messengers traveling throughout the body.
The circulatory system circulates fluids through your body. The endocrine system controls growth and body processes through the use of chemical messengers called hormones.

Yes, endocrine hormones act as chemical messengers. The circulatory system carries them to target tissues, where they carry messages to regulate body processes.
The endocrine system produces hormones which usually travel by way of the blood. Some don't have to travel very far and just diffuse through the tissues.
The hormones produced by the endocrine glands are secreted directly into the bloodstream. The circulatory system then distributes these chemical messengers to target tissues throughout the body.
The messages of the nervous system are relayed by nervous impulses, which are very fast and short-acting. In contrast, the messages of the endocrine system are sent via chemical messengers (hormones) distributed by the circulatory system. This distribution in your blood is much slower than the electrical impulses of the nervous system.
These two systems use different transmitters, which are chemical messengers called hormones in the endocrine system, and neurotransmitters that are followed by electrical impulses in the nervous system. The two paths that these two devices use are also completely different. Hormones travel throughout the body through the blood, while neurons transmit information through the nervous system
