Question
Renin is an important proteolytic enzyme produced by the kidney, involved in the control of salt/water balance in the body. Explain the source of renin, how it is secreted and how it acts to ultimately influence plasma volume. A separate hormonal system exists for directly controlling kidney water reabsorption. Explain how this hormone is released and how it exerts its renal effects.
