Homeostasis and hormones

Hormones

Hormones are chemicals secreted by glands in the body. Different hormones affect different target organs.

The bloodstream transports hormones from the glands to the target organs. Bodily reactions to hormones are usually slower and longer lasting than nervous reactions.

Move the mouse over the different glands to see what they do. You need to know the locations of the pancreas, ovaries and testes. You should also know which hormones they produce.
