Name something that happens in the body when core temperature rises above 37 degrees.
E.g. vasodilation, sweating, flattening body hairs, dehydration, reddening of skin.
Explain how hormones work to reduce blood sugar levels.
Pancreas detects increased blood sugar level and secretes more insulin and less glucagon. This causes the liver to store more glucose, thus reducing the amount of sugar in the blood.
Explain how a nerve impulse travels through a neuron.
What is a wombat's closest relative?
Koala.
Name the part of the brain that detects changes in blood water levels.
Hypothalamus
Name something that happens to the body when core temperature drops below 37 degrees.
E.g. shivering, vasoconstriction, body hairs stand up.
Explain how hormones work to increase blood sugar levels.
The pancreas detects decrease in blood sugar levels and secretes more glucagon and less insulin. This tells the liver to release more glucose, thus raising the amount of sugar in the blood.
