An pisyolohiya (etimolohiya sa Suanoy na Griyego: φύσις boot sabihon: naturalesa, ginikanan) iyo an  siyentipikong pag-aadal kan functions asin mechanisms sa sarong living system. Bilang sarong subdiscipline kan biyolohiya, nakapokus an physiology sa kun pàno an organisms, organ systems, indibidwal na organo, cells, asin an biomolecules nagdadara nin chemical asin pisikal na functions sa sarong living system. Segun sa mga klase nin organisms, an lado pwedeng bangaon sa medical physiology, animal physiology, plant physiology, cell physiology, asin comparative physiology.

Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. Physiological state is the condition of normal function. In contrast, pathological state refers to abnormal conditions, including human diseases.

An Nobel Prize in Physiology or Medicine iginawad sa Royal Swedish Academy of Sciences huli sa maorag na siyentipikong kapangganahan sa lado nin medisina na igwang kinaaraman sa pisyolohiya.
