internal environment

Значение термина internal environment в knolik

internal environment - internal environment
internal environment - Medium in which body cells are bathed i.e. the intercellular fluid. In equilibrium with blood-stream in vertebrates, it is normally kept highly constant in composition (homeostasis) e.g. in respect of osmotic pressure, content of individual ions, acidity and alkalinity (pH), and glucose concentration, by sensitive mechanisms which control these conditions in the blood, and hence in the intercellular fluid. Deviations from constancy have rapidly deleterious influence on cells, particularly on brain cells. Constancy is not always so complete in invertebrates.
