Controlling body temperature

Question 1

How does the body keep the core body temperature constant

Answer 1

By balancing the amount of energy lost and gained

Question 2

What is the thermoregulatory centre and where is it

Answer 2

-it contains receptors that ate sensitive to the temperature of the blood flowing through the brain and the skin temp
-the brain

Question 3

What happens when the body temp it too high

-temperature r… detect that the … body temp is too …
-the … centre acts as a … centre, receiving info from the temperature …, then triggering the … automatically
-effectors produce a … and counteract the c…

Answer 3

-temperature receptors detect that the core body temp is too high
-the thermoregulatory centre acts as a coordination centre, receiving info from the temperature receptors, then triggering the effectors automatically
-effectors produce a response and counteract the change

Question 4

What happens when the body temp is too low

-temperature r… detect that the … body temp is too …
-the … centre acts as a … centre, receiving info from the temperature …, then triggering the … automatically
-effectors produce a … and counteract the c…

Answer 4

-temperature receptors detect that the core body temp is too low
-the thermoregulatory centre acts as a coordination centre, receiving info from the temperature receptors, then triggering the effectors automatically
-effectors produce a response and counteract the change

Question 5

Body responses when you’re too hot

-… is produces by sweat … and e… from the skin, transferring … to surroundings
-v… -> bloods … supplying the skin d… so more blood flows c… to the surface of the skin, transferring … to surroundings

Answer 5

-sweat is produces by sweat glands and evaporates from the skin, transferring energy to surroundings
-vasodilation -> bloods vessels supplying the skin dilate so more blood flows close to the surface of the skin, transferring energy to surroundings

Question 6

Body responses when you’re are too cold

-… stand up to trap and … layer of …
-no … is produced
-… -> bloods … suppling skin c… constrict to close off … supply
-you s…, requires energy from … as muscles … which transfers some … to warm the b…

Answer 6

-hairs stand up to trap and insulating layer of air
-no sweat is produced
-vasoconstriction -> bloods vessels suppling skin capillaries constrict to close off blood supply
-you shiver, requires energy from respiration as muscles contract which transfers some energy to warm the body
