AQA GCSE Homeostasis-Questions with Correct Answers|Verified
Homeostasis - ✔✔The regulation of internal conditions to maintain optimum conditions in
response to changes
Stimulus - ✔✔A change in the environment
Receptors - ✔✔Cells that detect changes in the environment
Coordination centres - ✔✔Receive and process information from receptors. E.g. brain
Effectors - ✔✔Muscles or glands which bring about a response
Reflex action - ✔✔An automatic and rapid action
Endocrine system - ✔✔Consists of glands that release hormones into the blood to get to a
target organ to cause a response
Insulin - ✔✔Released from the pancreas in response to high blood glucose levels and causes
glucose to move from the blood into the cells. It causes glucose to be converted into
glycogen for storage in the liver
Glucagon - ✔✔Released from the pancreas in response to low blood glucose levels and
causes glycogen to be broken down into glucose and released back into the blood
Type 1 diabetes - ✔✔When the pancreas does not produce enough insulin
Type 2 diabetes - ✔✔When the body cells no longer respond to insulin
Oestrogen - ✔✔Released by the ovaries. Stops FSH being released and stimulates LH to be
released
