Claude Bernard in the context of "Physiologic"

Physiology (/ˌfɪziˈɒlədʒi/; from Ancient Greek φύσις (phúsis) 'nature, origin' and -λογία (-logía) 'study of') is the scientific study of functions and mechanisms in a living system. As a subdiscipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and 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.

A commemorative plaque, or simply plaque, or in other places referred to as a historical marker, historic marker, or historic plaque, is a plate of metal, ceramic, stone, wood, or other material, bearing text or an image in relief, or both, to commemorate one or more persons, an event, a former use of the place, or some other thing. Most such plaques are attached to a wall, stone, or other vertical surface.

Many modern plaques and markers are used to associate the location where the plaque or marker is installed with the person, event, or item commemorated as a place worthy of visit. A monumental plaque or tablet commemorating a deceased person or persons, can be a simple form of church monument. Most modern plaques affixed in this way are commemorative of something, but not all. There are also purely religious plaques, and some signify ownership or affiliation of some sort. A plaquette is a small plaque, but in English, unlike many European languages, the term is not typically used for outdoor plaques fixed to walls.

The internal environment (or milieu intérieur in French; French pronunciation: [mi.ljø ɛ̃.te.ʁjœʁ]) was a concept developed by Claude Bernard, a French physiologist in the 19th century, to describe the interstitial fluid and its physiological capacity to ensure protective stability for the tissues and organs of multicellular organisms.

William Banting (c. December 1796 – 16 March 1878) was a notable English undertaker. Formerly obese, he is also known for being the first to popularise a weight loss diet based on limiting the intake of carbohydrates, especially those of a starchy or sugary nature. He undertook his dietary changes at the suggestion of Soho Square physician William Harvey, who in turn had learned of this type of diet, but in the context of diabetes management, from attending lectures in Paris by Claude Bernard.
