The word physiology derives from the Latin "physiologĭa" and from the Greek "φυσιολογία" means "phisio" of "nature" and "lodge" is said to be of "study" or "treatise", physiology is about the science that studies organic beings in which they unite the beginning of precise knowledge, where they give meaning to those interactions of the basic components of a living being with its distribution and explaining the reason for each different situation, in which these components can be discovered. But it is also based on the knowledge of ideasthat are not linked to living beings such as thermodynamic, electricity, gravitational, meteorological laws , among others.
The Thermodynamics is the branch of physics that explains the states of equilibrium at the microscopic level constitutes a phenomenological theory, based on deductive reasoning, studying real systems, without modernizing and still an experimental method. Of electricity it is manifested by phenomena and physical properties. The gravity is linked with the energy of attraction that occurs between bodies endowed with mass. Meteorology is the science of several scientific disciplines of the atmosphere, which studies the weather, the atmospheric environment, the phenomena produced there and the laws that govern it.
For physiology to develop, ideas are needed both at the level of molecules and the organism in which the living being is able to exchange matter and force with the environment in order to reproduce. The hypothesis in physiology is that it fulfills a goal, in order to be accessible to those developments and functions of the living being and all its components at all levels.
The functions of the type of living organisms, can be differentiated into three that are, plant, animal and human physiology.
The plant physiology is in charge of the functions of the organs and tissues that are developed specifically for plants.
The physiology Animal studies the functions biological of various animal species that can be performed at the organ level.
The human physiology is the wisdom that studies the performance of multicellular beings is one of the most knowledgeable old world.
