The Lymphatic System is mentioned in the story of The Great River and represented in the ETC Montessori Human Physiology set, which means that I have three part cards for it upstairs in my Science Room. Thank goodness for nomenclature! That doesn't give me a narrative, though. In searching online for resources to help me create an accurate story of my own for this system, I found bunches of links, all of which had about one useful sentence. So I decided to create a blog post organizing all of them.
Happily, in taking the time to do this, I found something that worked well. The video lessons from Khan Academy were what finally saved me, because I felt like they actually explained it to me!
By the way, the story of the Great River calls this system The Department of Water Control.
