DEFINITION OF HOMEOSTASIS

Homeostasis is a key concept in understanding how our body works. It means keeping things constant and comes from two Greek words: 'homeo,' meaning 'similar,' and 'stasis,' meaning 'stable.'

Homeostasis is happening constantly in our bodies. We eat, sweat, drink, dance, eat some more, have salty fries, and yet our body composition remains almost the same. If someone were to draw your blood on ten different days of a month, the level of glucose, sodium, red blood cells and other blood components would be pretty much constant, regardless of your behavior (assuming fasting before drawing blood, of course).

Write a 8-10 line paragraph to explain what body systems are involved when you sit down to do your homework. Be sure to begin your paragraph with a topic sentence and include supporting details

Nervous system because you need the brain to think, muscular system, because you are writing with your arm and you are moving a part of your body and respiratory system, because we need to breathe to perform an activity

Research acclimatization. Is this process related to homeostasis? Explain this idea in a 3 line paragraph

No, because Homeostasis is any self-regulating process that protects an organism from changing environmental conditions and Acclimatization is the response of a body over weeks, months or a lifetime to long-term threats to homeostasis.
