Endocrine System, Part 1 - Glands & Hormones: Crash Course A&P #23

Hank begins teaching you about your endocrine system by explaining how it uses glands to produce hormones. These hormones are either amino-acid based and water soluble, or steroidal and lipid-soluble, and may target many types of cells or just turn on specific ones. He will also touch on hormone cascades, and how the HPA axis effects your stress response. Pssst... we made flashcards to help you review the content in this episode!
