Comorbidity describes two or more disorders or illnesses occurring in the same person. They can occur at the same time or one after the other. Comorbidity also implies interactions between the illnesses that can worsen the course of both.
History[ edit ] The classical era[ edit ] The study of human physiology Physiological disorders a medical field originates in classical Greeceat the time of Hippocrates late 5th century BC.
Hippocrates incorporated his belief system called the theory of humours, which consisted of four basic substance: Each substance is known for having a corresponding humour: Hippocrates also noted some Physiological disorders connections to the four humours, which Claudius Galenus would later expand on.
The critical thinking of Aristotle and his emphasis on the relationship between structure and function marked the beginning of physiology in Ancient Greece. Like Hippocrates, Aristotle took to the humoral theory of disease, which also consisted of four primary qualities in life: Unlike Hippocrates, Galen argued that humoral imbalances can be located in specific organs, including the entire body.
Galen also played off of Hippocrates idea that emotions were also tied to the humours, and added the notion of temperaments: Galen also saw the human body consisting of three connected systems: In the same year, Charles Bell finished work on what would later become known as the Bell-Magendie lawwhich compared functional differences between dorsal and ventral roots of the spinal cord.
In the s, the French physiologist Henri Milne-Edwards introduced the notion of physiological division of labor, which allowed to "compare and study living things as if they were machines created by the industry of man.
He later discovered and implemented antiseptics in the operating room, and as a result decreased death rate from surgery by a substantial amount. The Society is, "devoted to fostering education, scientific research, and dissemination of information in the physiological sciences.
It radically stated that organisms are made up of units called cells. Claude Bernard 's — further discoveries ultimately led to his concept of milieu interieur internal environment  which would later be taken up and championed as " homeostasis " by American physiologist Walter B.
By homeostasis, Cannon meant "the maintenance of steady states in the body and the physiological processes through which they are regulated. William Beaumont was the first American to utilize the practical application of physiology.
Nineteenth century physiologists such as Michael FosterMax Verwornand Alfred Binetbased on Haeckel 's ideas, elaborated what came to be called "general physiology", a unified science of life based on the cell actions,  later renamed in the 20th century as cell biology. Most recently, evolutionary physiology has become a distinct subdiscipline.
List of physiologists Women in physiology[ edit ] Initially, women were largely excluded from official involvement in any physiological society. The American Physiological Societyfor example, was founded in and included only men in its ranks.
Soon thereafter, inJ. Haldane proposed that women be allowed to formally join The Physiological Societywhich had been founded in SkeltonSarah C. Gerty Cori along with husband Carl Corireceived the Nobel Prize in Physiology or Medicine in for their discovery of the phosphate -containing form of glucose known as glycogenas well as its function within eukaryotic metabolic mechanisms for energy production.
Moreover, they discovered the Cori cyclealso known as the Lactic acid cycle,  which describes how muscle tissue converts glycogen into lactic acid via lactic acid fermentation. Barbara McClintock was rewarded the Nobel Prize in Physiology or Medicine for the discovery of genetic transposition McClintock is the only female recipient who has won an unshared Nobel Prize.
Buck along with Richard Axelreceived the Nobel Prize in Physiology or Medicine in for their discovery of odorant receptors and the complex organization of the olfactory system. Elizabeth Blackburn along with Carol W. Greider  and Jack W. Szostakwas awarded the Nobel Prize for Physiology or Medicine for the discovery of the genetic composition and function of telomeres and the enzyme called telomerase.Psychological issues can affect a person's physical body.

Physiology (/ ˌ f ɪ z i ˈ ɒ l ə dʒ i /; from Ancient Greek φύσις (physis), meaning 'nature, origin', and -λογία (-logia), meaning 'study of') is the scientific study of the functions and mechanisms which work within a living system.. As a sub-discipline of biology, the focus of physiology is in how organisms, organ systems, organs, cells, and biomolecules carry out the chemical.
