Take an Endocrine System Siesta
Our memorization suite, Study Putty, is secreting new content all the time. We’ve squeezed our brain-glands in order to produce learning tools on the topic of the oozy ol’ endocrine system.
Here you can memorize the names and locations of the endocrine glands. You can test yourself: given certain organs, what is endocrine and what is exocrine? You can also match important endocrine hormones to the glands that chiefly produce them.
A game of gland locations. Notice only four show at once–hit “new game” for a new set.
