I agree with what everyone has said so far. If you like the courses that Physiology requires then you may as well go into it so you are guaranteed them. Otherwise if you are planning on pursuing schooling or a job that doesn't have to do with either it doesn't make a big difference.
I personally went into it despite planning on applying to other things unrelated to Physiology because doing a masters in on my list of possibilities (also because I like the subject matter obviously). I knew of all the streams I would prefer physiology and would then have all the courses and "degree" to give me a
slight upper hand in applying to the labs I would be applying to.
Also just as a side note, I believe your minor is listed on your degree!
