What is temperature?Show answer
If body temperature rises, the body sweats (evaporation removes heat) and skin blood vessels widen (heat is lost); if it falls, the body shivers (muscle activity generates heat) and skin vessels narrow (heat is conserved). Both responses push temperature back toward about 37 degrees Celsius.
What is blood glucose?Show answer
After a meal, blood glucose rises. The pancreas releases insulin, which makes cells take up and store glucose, lowering it. Between meals, glucose falls and the pancreas releases glucagon, which makes the liver release stored glucose, raising it.
What is water balance?Show answer
When the body is short of water, hormones make the kidneys reabsorb more water, producing less, more concentrated urine; when there is excess water, more dilute urine is produced. This keeps the body fluids at a stable concentration.
What is q1?Show answer
Define homeostasis. [2]
What is q2?Show answer
Explain why negative feedback is described as self-correcting. [2]
