Lec 1 INTRODUCTION TO PHYSIOLOGY and its branches.pptx

Introduction of physiology and discussion of various branches of physiology. Here you'll find definitions of physiology, difference between clinical and applied physiology, definition of neurophysiology, nutrient physiology, cellular physiology cardiovascular physiology, pathophysiology and importance of physiology. Here you'll find why understanding of physiology is important for healthcare professionals and medical students

1. INTRODUCTION TO PHYSIOLOGY

2. What is physiology The term physiology is a combition of two greek words Physis means nature Logos mean science or study Physiology is the science that treats the functions of living organisms and its parts.

3. Medical physiology It is the foundation for modern medicine. Human body deviate from normal function is called disease or pathological condition

4. Aims of physiology T o understand mechanism (process) behind the functions of a living system. To understand how the cells, organs, organs system work and how it is integrated at the organism level. To determine what goes wrong in disease, facilitating the discovery of new diagnostic, treatment and preventive measure. To explore the system of human body and relate their functions to homeostasis. To understand what various organs of body do to contribute to the overall physiology of body as well as the interaction between them

5. Branches of physiology Applied physiology Clinical physiolgy Nutrition physiology Cardiovascular physiology Neurophysiology Pathophysiology

6. Applied Physiology Applied physiology is the study of biological systems and steps into practice. Clinical physiology Clinical physiology is a diagnostic speciality to which patients are reffered to undergo specialized tests of functions of heart, blood vessels, lungs, kidneys and other organs.

7. Nutrition physiology Nutrition physiology deals with how the bodies extracts the nutrients from food, how obtain the energy, utilize nutrients and all is related to health and disease. Cardiovascular physiology The study of fuctions of the heart and blood vessels. Neurophysiology The study of functional properties of nerve cells .

8. Pathophysiology Phathophysiology is the study of physical and functional changes that occurs during a disease process. Why pathophysiology is important for medical students and physicians:- It helps to find answers to important questions What is cause of disease and why the disease is developing. What are mechanisms responsible for development of symptoms and signs of disease.
