I'm too much of a layman on this topic to be of help, but for the sake of my own understanding:

I'm not too sure why being an African is supposed to afford special biological knowledge, but I believe from what you've said her claim is that the recurrent laryngeal nerve provides the heart with feedback on the pressure of blood flow to the head. And the recurrent laryngeal nerve doesn't actually do that?

I guess from my own perspective (and I don't know how biologically savvy your audience is here) a plain English statement amounting to "It doesn't do that. Here's what it does do..." with the function of the nerve filled in would be the clearest approach.

Edit: Typo.
