I like Dr. Ahern's lectures, I think he is the best in this program. He's very straight forward, precise, concise and connects different points related to what he's talking. After seen these videos I went ahead and did a q-bank of a different program and nailed the ones related to this thanks to his lecture. Some people need to keep in mind that these lectures are not going to cover every single detail, but unlike lectures from others study courses, they do cover more than the basics. For broader information with specific details you definitely need to read textbooks (e.g. Guyton, Robbins, Harrison's) and " google" it up.
I couldn't follow this lecture - it was not presented well at all.
