In the typical A&P course, students get the message that sodium and chloride are essential to life. In fact, throughout the course they learn about many of the central roles these ions play in the function of the human body.
It's no wonder that salt has played such a central role in human history. Which reminds me of a great book I listened to (it was the audio version) a couple of years ago. Salt: A World History (by Mark Kurlansky) ought to be on your list of "must read books for A&P professors."
Besides learning about salt, you'll also come away with an appreciation of the interconnectedness of things.
If nothing else, it will give you a lot of anecdotes and factoids that you can use in your A&P class.
One of the questions that I often get in class is, "if salt [or sodium] is so essential to life, why is it bad for you?" Wow, what a great teaching moment! I can help bring the student to a higher level of thinking by dissecting the false choice of "good" and "bad" in this case and revealing the "gray."
But of course, what is the latest story on the role of salt in creating hypertension (HTN) or other problems? Check out this recent article from the LA Times to help sort out the latest thinking on this one:
