Physiology is the logical investigation of capacities and instruments in a living framework. As a sub-order of science, physiology centers around how life forms, organ frameworks, singular organs, cells, and biomolecules complete the substance and physical capacities in a living framework. As indicated by the classes of living beings, the field can be partitioned into clinical physiology, creature physiology, plant physiology, cell physiology, and near physiology.

Fundamental to physiological working are biophysical and biochemical procedures, homeostatic control systems, and correspondence between cells. Physiological state is the state of typical capacity, while neurotic state alludes to strange conditions, including human illnesses.

The Nobel Prize in Physiology or Medicine is granted by the Royal Swedish Academy of Sciences for excellent logical accomplishments in physiology identified with the field of medication.
