Why does muscle activity affect the temperature of the body?Multiple ChoiceThe rate of chemical reactions increases in muscle fibers during contraction, so the rate of heat production also increases.Muscle contraction generates pyrogens, which reset the body's internal thermostat to a higher temperature.Muscle activity directs more warm blood to the muscles away from the central core, causing a cooling effect on your internal organs.Increased muscle activity causes a rise in adipose stores, which increases the insulation value of the body.

Use the following terms to correctly complete these sentences regarding the creation of body temperature through muscle metabolism.Chemical reactions within cells release some energy in the form of .The rate of chemical reactions in a muscle cell directly related to the rate of contraction in muscle fibers.Therefore, an increased use of muscles results in a(n) rate of heat production.This causes an increased temperature.Through the use of sweating and skin blood vessel , body heat is lost, thereby returning body temperature to normal, which serves to maintain .When body temperature drops, increased heat production occurs through .

Body temperatureMultiple Choicewill increase after blood vessels in the skin constrict.decreases when the rate of the chemical reactions increase.is lowered by shivering.results from the heat produced when muscles contract.is raised by sweating.

Muscle glycogenolysis is higher during exercise in the heat partly because:Group of answer choicesplasma adrenaline levels are increasedskeletal muscle blood flow is reducedmuscle temperature is lower

When environmental air temperature exceeds skin temperature and relative humidity increases during exercise, heat is lost by the body through convection and/or radiation. sweat is evaporated more easily. the sweat rate volume increases. heat is gained by the body through conduction.
