This reduces the body water level and is dangerous for the survival of the cells; therefore the cells send a message to the brain. The brain analyses the situation and sends a message to the pituitary gland asking it to release a hormone called ADH (anti-diuretic hormone). ADH is in fact a message to the kidney, telling it to absorb water from the blood and send it back to the cells. After it has refilled the water level, the brain tells the pituitary gland to stop sending ADH to the kidney as there is no more need for water. On the other hand, if an individual has too much intake of fluids, the brain will make sure that the pituitary gland does not send ADH to the kidney. In the absence of ADH the kidney will not absorb any water but excrete it out in the form of urine. This is how the nervous, endocrine, urinary and circulatory systems interact with each other to regulate the water levels in the
