What do receptors, processing centre and effectors do?
Receptors detect the change in our body. i.e Temperature change. Processing centre gets this information and coordinates a response. The effector produces this response
2 of 6
What is negative feedback
Negative feedback ensures that, in any control system, changes are reversed and returned back to the set level.

How do the kidneys maintain our water balance?
The kidneys maintain our body's water balance by controlling the water concentration of blood plasma.The kidneys also control salt levels and the excretion of urea. Water that is not put back into the blood is excreted in our urine.

How does the body maintain water balance ?
The kidneys maintain our water balance by producing urine of different concentrations.
5 of 6
How ?
When the water level of our blood plasma is low,more water is reabsorbed back into the blood and the urine becomes more concentrated. When the water level of our blood plasma is high, less water is reabsorbed back into the blood and our urine is more
