1.

Homeostasis is

the removal of waste
growth
the maintenance of a constant internal environment
reproduction
2.

When blood glucose concentration is too high, the pancreas secretes

glucagon
adrenaline
insulin
oestrogen
3.

Glucagon causes

glucose to be converted to glycogen
glycogen to be converted to glucose
glucose to be excreted
insulin release
4.

Sweating cools the body because

evaporation of sweat removes heat from the skin
sweat is cold
it blocks blood flow
it makes hairs stand up
5.

In vasodilation

arterioles narrow
sweating stops
shivering begins
arterioles near the skin surface widen so more heat is lost
6.

Shivering

generates heat by respiration in contracting muscles
cools the body
loses heat by evaporation
widens arterioles
7.

Body temperature is monitored by the

heart
liver
brain (hypothalamus)
kidneys
8.

Negative feedback means

a change from the set point causes a response that reverses the change
a change is made larger
no response occurs
hormones are destroyed
9.

Fatty tissue under the skin

produces sweat
contains receptors
makes hair
insulates the body against heat loss
10.

In type 1 diabetes

too much insulin is made
the pancreas does not produce enough insulin
glucagon is absent
the liver stores too much glycogen
