Exam 15: Energy Balance and Temperature Regulation

Skin vasoconstriction increases the skin's insulative capacity.

If more energy is contained in the food eaten than is expended,what happens?

The only means of heat loss when the environmental temperature exceeds core temperature is ____________________.

An animal can be driven to overeat either by selective stimulation of the appetite centres or destruction of the satiety centres.

We lose or gain heat through ____________________ to the layer of air in direct contact with our bodies.

What is the major means of decreasing heat loss in response to a cold environmental temperature?

Match the term with the correct characteristic by using the answer code: -freezing of tissues as a result of cold exposure

When the surrounding temperature is low,how is heat NOT lost from the body?

Which statement is true of the vasoconstriction of the blood vessels to the skin?

Match the term with the correct characteristic by using the answer code: -morbid fear of becoming overweight

What does not characterize heat exhaustion?

Which statement concerning leptin is correct?

Oral temperature is the same as core temperature.

How can a person lose heat to an environment warmer than the body?

What does NOT act as a satiety signal?

Metabolic rate equals energy expenditure/unit of time.

An elevation in body temperature due to reasons other than an infection is known as ____________________.

Radiation and conduction are two types of heat exchange between the body and environment.What determines the magnitude of heat loss via these two processes?

The core temperature is maintained at a fairly constant level,but skin temperature is quite variable.

The stimulation of gastric ____________________ receptors as food accumulates in the stomach can suppress the intake of food.
