What is homeostasis? | Live Science A familiar example of homeostatic regulation in a mechanical system is the action of a thermostat, a machine that regulates room temperature. Any system in dynamic equilibrium tends to reach a steady state, a balance that resists outside forces of change. If blood glucose concentration rises above the normal range, insulin is released, which stimulates body cells to remove glucose from the blood. The definition of homeostasis is the ability or tendency to maintain internal stability in an organism to compensate for environmental changes. The circulatory system also plays important roles: its baroreceptors (pressure-sensitive receptors in the blood vessels that respond to stretching) relay blood pressure information back to the brain, and it transports hormones secreted by the hypothalamus and the thyroid gland to regulate the bodys metabolism. For instance, when there is a hemorrhage (loss of blood), it will cause a sequential activation of clotting factors.
