Homeostasis refers to metabolic balance maintained by several processes. The human body has several examples of homeostasis.
Glucose concentration refers to the amount of glucose – blood sugar – present in the bloodstream. The body uses glucose as a source of energy, but too much or too little glucose in the bloodstream can cause serious complications. The body uses hormones to regulate glucose concentration. Insulin reduces glucose concentration, while cortisol, glucagon and catecholamines increase glucose concentration.
