Exam 15: Fluid and Acidbase Balance

Which of these actions happens during fever?

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

Upon exposure to heat, skin vasodilation occurs, which increases the temperature gradient between the skin and environment, thus promoting heat loss.

The normal core temperature is 37°C.

What type of heat loss occurs by sitting on a cold car seat?

The temperature control centre in the posterior region of the hypothalamus is activated in response to exposure to cold.

Hyperthermia-associated, abnormally high levels of thyroid hormone elevate the core temperature by increasing the rate of metabolic activity.

____________________ refers to the obligatory increase in metabolic rate incurred during the processing and storage of ingested foods.

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

The inner core includes the abdominal and thoracic organs.

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

Which of these factors does NOT impact the variance of "normal" body temperature?

Leptin is a hormone released from adipose tissue.

Which of these is NOT a means of generating or holding heat in the body?

Heat can be lost directly to the external environment by the vasodilation of blood vessels in which of these body parts?

Which one of these factors does NOT increase metabolic rate?

The amount of heat lost to the environment by radiation and conduction-convection is largely determined by the ____________________ between the skin and the external environment.

Neuropeptide Y is a strong appetite inhibitor.

Match the terms labelled a. through g. with the correct characteristic. a.hypothermia b.obesity c.frostbite d.hyperthermia e.anorexia f.heat stroke g.heat exhaustion -slowing of all body processes as a result of generalized cooling

____________________ refers to a state of collapse resulting from reduced blood pressure brought about as a consequence of overtaxing the heat loss mechanisms.
