Are you an adrenaline junkie? Then we've got the pin for you -- celebrate your adrenals, the glands in charge of making you look for your next big rush. This cute little 1.25" printed aluminum pin comes packed on a card and was made in China. What do adrenal glands do? Most famously, the adrenal glands squish out the hormone adrenaline, which controls the body’s fight or flight response by speeding up your heart rate and otherwise pumping you up. The adrenal glands sit atop your kidneys and work with the hypothalamus and pituitary glands to regulate metabolism, stress and immunity. They also produce cortisol, another stress hormone, and androgen sex hormones. What a pair! Life’s more exciting with adrenal glands!
