Chapter 2, Problem 4AWK
Summary Introduction
To review:
The change in perception of temperature affected by the amount of humidity in the atmosphere.
Introduction:
Water, in the human body, accounts for 60% of total body weight. It plays an important role in maintaining the body temperature. This is because water is capable of holding and absorbing large amounts of heat energy. The body adjusts its temperature with respect to the atmospheric temperature.

- In some diseases, an infection causes a high fever, resulting in a crisisstate. Once body temperature begins to return to normal, the person ison the way to recovery. If you were looking for symptoms in a personwho had just passed through the crisis state, would you look for dry,pale skin or flushed, wet skin? Explain.arrow_forwardIn mammals, body temperature is controlled by a structure in the brain called the hypothalamus. The hypothalamus is able to sense even slight variations in body temperature. This structure is responsible for bodily responses that include thirst, the activation of sweat glands, and the dilation of blood vessels near the skin. Each of these mechanisms works to restore body temperature to a normal range.arrow_forwardDuring a bacterial infection, the pathogen and the immune system send signals to the hypothalamus suggesting that temperature is set too low.
