Thermoregulation

Why is the inability to sweat (anhidrosis) dangerous?

• It results in high blood glucose.

• It can lead to high blood pressure.

• It prevents your body from cooling down when it's too hot.

• It helps your body regulate carbon dioxide levels.

Put the following steps in the correct order.

• brain detects a rise in body temperature

• nervous system sends signals to the skin

• body temperature returns to norma

• body temperature starts to decrease

• blood vessels dilate & sweat is released

The receptors in the hypothalamus (in the brain) detect changes in the temperature of the

• skin

• blood

• muscles

• hair

Organize these options into the right categories

Groups:

(a) response to increase in body temperature

,

(b) response to a decrease in body temperatu

,

(c) detects blood temperature

,

(d) detects extremity temperature

• muscles cause shivering

• blood vessels constrict

• blood vessels dilate

• nerves in skin

• sweating stops

• brain

• sweat is produced
