Homeostasis: The relative constancy of the internal environment Steady state vs. equilibrium

The body: A society of interdependent cells, each type with its own needs and contributions.

O2O2

Cell Membrane: selectively permeable Capillaries: highly permeable except to proteins

Homeostasis Regulated via reflex arcs and naturally maintained by the process of negative feedback Measurement –Which physiological variables? –Averages and ranges
