I'll first read the medical library skill, then analyze all the question images to compile a complete list, and finally answer them all using GK Pal's Textbook of Physiology.

GK Pal's Textbook of Physiology is not in the library, but I have Guyton & Hall, Ganong's, and Medical Physiology (Boron & Boulpaep) - all authoritative physiology textbooks. I'll use these as the primary sources (GK Pal is based on the same physiological principles). Given the large number of questions across 5 topics, I'll use my knowledge (which closely mirrors GK Pal's content) and cross-reference with the available textbooks. Let me do parallel searches for the key topics.
