Where are most hormones transported?
The action of hormones is determined by numerous factors such as its pattern of secretion and the response of the receiving tissue (signal transduction response). Though few hormones circulate dissolved in the blood-stream, most are carried in the blood, bound to plasma proteins.
Are hormones transported substances?
A hormone is defined as ‘a chemical transmitter substance produced by cells of the body and transported by the bloodstream and other means to the cells and organs which carry receptors for the hormone and on which it has a specific regulatory effect’ (Blood and Studdert, 1999).
What system transports hormones around the body?

Are hormones transported through nerves?
They both employ chemicals to transmit messages and respond to stimulus caused by changes in their environments. The responses of the nervous system, are usually instantaneous. Hormones are transported all over the body via the blood, so response times will vary.
What do hormones do in your body?

What is the difference between nerves and hormones?
There are important differences between the two systems as described in the table….Hormones and nerves.
| Nervous | Hormonal | |
|---|---|---|
| Transmission of signal | By nerve cells | By the bloodstream |
| Effectors | Muscles or glands | Target cells in particular tissues |
