homeostasis

Question 1

homeostasis

Answer 1

the process of maintaining a constant internal environment despite external changes

Question 2

negative feedback (homeostasis)

Answer 2

happens when important variable deviates from normal range or limit
response is produced to counteract the deviation

Question 3

low body temperature (homeostasis)

Answer 3

hypothalamus activates warming mechanism
blood vessels constrict so blood is diverted to deeper tissue
muscles contract causing you to shiver
body temp increases

Question 4

high body temperature (homeostasis)

Answer 4

hypothalamus activates cooling mechanism
blood vessels dilate and capillaries fill with warm blood
sweat glands produce sweat
body temp decreases

Question 5

high blood sugar (homeostasis)

Answer 5

high blood sugar promotes insulin release
pancreas produces insulin
this stimulates glycogen formation through liver
and glucose uptake from blood
lowers blood sugar

Question 6

low blood sugar (homeostasis)

Answer 6

low blood sugar promotes glucagon release
pancreas produces glucagon
stimulates glycogen breakdown through liver
rises blood sugar
