The example below is a homeostatically regulated system. Decrease in blood volume ? triggers volume receptors in atria (heart) ? Signals hypothalamus (brain) to synthesize a neurohormone ? Neurohormone is released ? Kidneys increase number of water pores in renal cell membranes ? increases blood volume * Reminder: You don’t need to know anything about water regulation, use your fundamental knowledge regarding homeostatically regulated systems 1.) In this system presented identify the following variables and explain what is the function...
