Another great lesson. It focuses on hormones, gives important examples of hormones and the dysfunctions that they can cause. Nevertheless the lesson does not stray from the topic. Different organs produce different hormones that are secreted into the bloodstream and then can attach to specific receptor molecules, thereby modifying cell behavior. That’s a good place to start!
