Not sure if anyone already put it up.. but this is a site with info and a video on how the thyroid gland secretes thryoxine and its various reactions with other cells.

This is your typical, article-type website. But what stuck out to me was the list of endocrine-related diseases, and that's why I picked it. So, this site has a basic, yet detailed overview of the endocrine system along with links to info about diseases such as Thyroid cancer- a cancer I never even though existed.
