Final answer:
Homeostasis refers to maintaining internal conditions in a steady state, while allostasis is the process of adapting to stressors.
Step-by-step explanation:
Homeostasis and Allostasis
Homeostasis refers to the relatively stable state inside the body of an animal, where various internal conditions are maintained.
Examples include blood glucose level, body temperature, and blood calcium level. Homeostatic mechanisms use negative feedback to restore these conditions to their normal range if they deviate. Allostasis, on the other hand, is the process by which the body adapts to stressors and maintains stability in the face of change. It involves the activation of various physiologic systems, such as the endocrine system and the immune system, to cope with stress.
Examples of Stressors
Stressors are external or internal factors that can disrupt homeostasis and trigger a stress response. Some examples of stressors include:
Physical stressors: such as extreme temperatures, physical injury, or strenuous exercise.
Psychological stressors: such as academic pressure, relationship problems, or financial difficulties.
Environmental stressors: such as pollution, noise, or natural disasters.
Chemical stressors: such as toxins, drugs, or alcohol.
