Homeostasis is really important for keeping living things alive. It helps them control what happens inside their bodies, even when things change outside. Here are some key points about homeostasis:
Keeping the Right Temperature: Mammals, like humans, try to keep their body temperature around 98.6°F (or 37°C). If it gets too hot or too cold, it can mess up how our bodies work, which can be dangerous.
Balancing pH Levels: Our blood has to stay at a balance called pH, which is between 7.35 and 7.45. If it changes a lot, it can hurt our cells. For example, a pH of 6.8 can cause a condition called acidosis, while a pH of 7.8 can lead to alkalosis.
Keeping Water Levels Steady: Our bodies are made up of about 60% water, and having the right amount is key for our cells to work well. Our kidneys help with this by filtering about 180 liters of blood every day and keeping 99% of the water we need.
Regulating Nutrients: Living things also need to keep their sugar levels balanced to get energy. For example, normal blood sugar levels should be between 70 and 130 mg/dL.
These processes show us how homeostasis helps living things stay healthy and adjust to different situations around them.
