These are the very important question (ViP) for Physiology paper 1 and 2 simultaneously…
First prepare the orange highlight topics than prepare other remaining topics…
for examination point of view, well let me outline some units for you in a decreasing order, according to my view. I don't know about your examiners mindset yhough. :P
Cardiovascular System
Central Nervous System
Blood
Renal Physiology
Respiratory Physiology
Nerve Muscle Physiology
Endocrine Physiology
Reproductive Physiology
You might get a few questions from Autonomic Nervous System, I can't really say though, but ANS is a very important topic. You should have maximum understanding of it. Why?
Well because, if you know ANS well, and your receptors well, Pharmacology will be quite easy for you.
