Physiological condition or, more often "physiological conditions" is a term used in
biology,
biochemistry, and
medicine. It refers to conditions of the external or
internal milieu that may occur in nature for that organism or cell system, in contrast to artificial
laboratory conditions. A temperature range of 20-40 degrees Celsius, atmospheric pressure of 1, pH of 6-8, glucose concentration of 1-20 mM, atmospheric oxygen concentration, and earth gravity are examples of physiological conditions for most earth organisms.
