Physiology is a Greek word (Physis: nature; Logos: discourse). The term was coined by Jean Fernel, A French Physician.  'Physiology' is the scientific  study of normal functioning of the living system. Human Physiology is concerned with the way the human system function and contributes to the functioning of the human body as a whole.

At the undergraduate level, it is a subject of importance as it apprises the students about the functioning of normal human body and forms the basis of medicine. The  under standing of Physiology is thus absolutely essential for study and practice of medicine.The diseased states can be viewed as Physiology “gone wrong” & for this reason an understanding of Physiology is absolutely essential for study and practice of medicine.

Apart from this,  human physiology based on the research activities is sub divided into applied and non-applied Physiology. Applied Physiology covers various streams like neurophysiology, Renal Physiology, Respiratory Physiology, Skin Physiology, Sleep Physiology and is studied at the post graduate level. Non-applied Physiology which the undergraduate students are apprised of comprises the basic study of Physiology.

The department of physiology was established as a part of Medical College in 1997. The major contribution for setting up the department was given by  Dr. J. L. Agarwal, who was Professor & Head of the department from the year 1997 to 2008.
