Human Physiology

Human physiology is the science of the mechanical, physical, bioelectrical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. In simple terms "Human Physiology" is the study of the body and its functions in each of the different system in any living body .Physiology focuses principally at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.

The Concept of Hemeostasis

The term "Homeostasis" refers to the maintenance of overall inner resistance in the body. Homeostatic stable the body by regulating internal environment at the body surface.These kinds of conditions are requited in order to make body keep functioning. Homeostatic procedure is essential for the survival of each cell.Homeostasis in a general sense refers to stability, balance or equilibrium. Maintaining a stable internal environment requires constant monitoring and adjustments as conditions change. This adjusting of physiological systems within the body is called homeostatic regulation.


Traditionally, the academic discipline of physiology views the body as a collection of interacting systems, each with its own combination of functions and purposes.Each body system contributes to the homeostasis of other systems and of the entire organism. No system of the body works in isolation, and the well-being of the person depends upon the well-being of all the interacting body systems.
