Activity 3: examining the e ect of temperature on heart rate. Organisms that usually maintain the same internal body temperature in spite of environmental temperature changes are. The general name for the process that maintains the internal body temperature in humans is. The electrolytes in a ringer"s solution are required to. An internal body temperature that is above the normal range is. What e ect do you think a fever of 104 f would have on heart rate? https://media. pearsoncmg. com/bc/bc_0media_ap/physioex/10/ex6/act3/ You scored 100% by answering 4 out of 4 questions correctly. In the 5 c ringer"s solution, the frog heart. In the 32 c ringer"s solution, the frog heart. You correctly answered: a decrease in heart rate. You correctly answered: spontaneous cardiac action potentials would not occur. Explain the e ect that decreasing the temperature had on the frog heart. When there is a decrease in temperature the heart rate gets slower.

How do endothermic animals like seals and foxes âknowâ thattheir body temperature needs to be adjusted?

	1.	When shivering starts they know itâs time to warm up
	2.	Nerve cells in their brains measure the temperature of blood andsend signals to other cells and tissues if the temperature changesvery much one way or the other
	3.	Reduced mobility, sluggishness, are all signs of too-low bodytemperature
	4.	Temperature-sensing cells in their extremities (eg, legs andfeet) measure the environmental temperature and signal the brainthatâs itâs time to change body temperature

Which of the following statements are true about dehydration? Select ALL that apply.

a. Dehydration increases heart rate, skin temperature, and blood viscosity.

b. Dehydration decreases cardiac output, blood plasma volume, and muscle blood flow.

c. Even slight dehydration can result in measurable physiological changes.It's best to hydrate before, during, and after exercise.

d. Dehydration increases stroke volume, central blood volume, and muscle blood flow.

e. All humans sweat at the same rate based on the temperature of their environment.

f. Dehydration helps people regulate their body temperature in hot environments.

Which of the following statements are true about hyperthermia, body temperature, and fatigue? Select ALL that apply.

Select one or more:

a. In general, as relative humidity increases, time to exhaustion decreases.

b. A hydrated person cannot experience hyperthermia.

c. As core body heat increases, blood flow to the skin increases to promote heat loss and reduce body temperature.

d. Warming up before an event allows the body to heat up at a slower rate and decreases the chance of hyperthermia.

e. As core body temperature increases, blood glycogen is broken down faster, sweat rate increases, and the risk of dehydration is greater.

f. Hyperthermia occurs when core body temperature increases past a normal, healthy level.

g. Hyperthermia only occurs in cold environments.
