05 · How the Body Maintains Stability: Regulation, Feedback, and Adaptation
Meals, standing up, exercise, and changing weather all alter the demands on the body. Keeping temperature, glucose, and blood pressure within workable ranges requires continuous regulation. Homeostasis describes this dynamic stability, not an unchanging set of readings.
18 · Hormones, endocrine systems and feedback
Hormones carry information through body fluids, but responses require suitable receptors and cellular conditions. Endocrine reasoning connects signal sources, receptors, feedback and timing.
