Overview & Comparison of Water- vs Lipid-Soluble Hormones

The video introduces the endocrine system, highlighting its role as a major control system alongside the nervous system. It explains the production and release of hormones by glands, differentiating between endocrine and exocrine glands. The video delves into the two main classes of hormones: water-soluble and lipid-soluble, detailing their mechanisms of action.
