Scientific Practices Follow the Hormone
Using the Internet as a resource, identify a hormone produced by a healthy thyroid and then find two roles it plays in the body. How does the hormone travel from the thyroid to those organs?

Interpretation:
A hormone produced by a healthy thyroid and its role in the body has to be identified. The way in which the hormone travels from thyroid to organs has to be determined.
Concept Introduction:
Hormones: Hormones are chemical messengers which are secreted by the cell in endocrine system and are transported along the blood to stimulate the target cells having the corresponding receptors.
Thyroxine molecule is nonpolar hormone produced by thyroid.
Explanation of Solution
An example for a hormone produced by a healthy thyroid is thyroxine. Thyroxine helps in regulating the rate of metabolism and in maintenance of the bones.
Thyroxine is a hormone and is secreted directly to the blood to reach the target organs.
