What are some ways that the human body responds to internal changes such as the presence of excess salt?

First of all, the change in internal conditions is registered by a chemo-receptor, like in the case of excess salt. This receptor in turn releases kinases, which signal the cell to produce a signalling molecule that will affect another cell's receptor or it's own receptor, depending on the circumstances. This chain reaction continues until it reaches a final effector cell which tackles the problem of higher salt concentration, like in this case, vasopressin would be released to dilate the blood vessels so that larger volume of water would flow. This volume is retained by the nephrons in kidney by reabsobing water from the urine formation process. The higher volume of water will dilute the excess salt and homeostasis would be maintained.
