An organism whose body temperature is strongly correlated to that of its external environment is called what?
The body has a built-in thermostat called the hypothalamus, which acts as a control center for regulating body temperature. It works by sending signals to different organs and systems in the body, such as the skin, muscles, and blood vessels, to either conserve or release heat to maintain a stable internal temperature.
The average normal body temperature for humans is around 98.6°F (37°C). However, this can vary slightly from person to person and can also fluctuate throughout the day. A temperature above or below this range may indicate an underlying illness or infection.
The external environment can greatly influence body temperature. When the external temperature is high, the body responds by sweating and increasing blood flow to the skin to release heat and cool down. On the other hand, when the external temperature is low, the body responds by shivering and constricting blood vessels to conserve heat and keep the body warm.
If the body temperature rises above 104°F (40°C), it can lead to heat stroke, which is a medical emergency. Symptoms include confusion, dizziness, and loss of consciousness. A body temperature below 95°F (35°C) can lead to hypothermia, which can cause shivering, confusion, and even death if not treated promptly.
As we age, our bodies become less efficient at regulating temperature. This is because older adults have a decreased ability to sense changes in temperature and may also have underlying health conditions that affect their body's response to temperature changes. Therefore, it is important for older adults to take extra precautions in extreme temperatures to avoid heat stroke or hypothermia.
