Basic overview of human physiology

Abstract

Physiology has been defined as the branch of science dedicated to analyze and understand all the events, activities and functions of the living system. It is the study of normal function and vital processes of living organism. Classified as the sub-section and subdivision of biology and zoology, it covers a range of subject that include organs, anatomy, cells, biological compounds, and how they all interact to make life possible. The different division of physiology are only the various attempts to approach and understand the same problem from different angle. System biology considers all living phenomena as emergent properties due to interface among components of the system. Each system is highly complicated and each functions properly only when it cooperates with the other in maintaining the proper internal environment. The present knowledge of physiology has already assumed gigantic proportion and recent researches are adding everyday something new to it. The present review gives an idea about the major human physiological process like movement, digestion, respiration, blood circulation their composition and functioning and how each system are interrealated affecting functioning of other regulating the body function. © 2020 Elsevier Inc.
