Physiology explains how the body’s systems function under normal and pathological conditions. This book covers key concepts in cardiovascular, respiratory, renal, digestive, endocrine, and nervous system physiology. It explores homeostasis, feedback mechanisms, and physiological responses to stress and injury. Assessment techniques such as ECG, spirometry, and blood pressure monitoring are included. Diagrams, case examples, and practical exercises aid comprehension and clinical application. The text supports paramedics and healthcare trainees in linking physiological principles to patient assessment and care.
