Feedback to control centre: A message about the osmotic pressure in the blood is sent through nerves to the control centre in the brain. The control centre is

able to interpret this information and respond by regulating the amount of water and salts in the blood to maintain proper osmotic balance. This feedback loop helps to ensure that the body's fluids are kept in the correct balance, which is essential for overall health and well-being. The control centre plays a crucial role in maintaining homeostasis in the body and responding to changing conditions to keep the internal environment stable.
