The various sections of this book including those on hematology, human experiments and clinical physiology have been thoroughly revised as per the competency-based medical education curriculum (NMC) guidelines. We have attempted to familiarize the students with the clinical and experimental approach to human physiology. Well-labeled diagrams and flowcharts have been incorporated to improve the understanding. The book has been specially designed for step-by-step learning of practicals and experiments, which are essential for medical students seeking to develop expertise in physiology and clinical medicine. This tenth edition features numerous revised and redrawn illustrations to facilitate the easy assimilation of the practicals.
