1.	What are cardinal points ? How does they affect the physiological process ?
Answer» A factor influencing a physiological process has three principle values called cardinal points, minimum, optimum and maximum. (i) The minimum of a factor is that valiue below which the physiological process cannot continue. (ii) Optimum value is that point where the physiological process can continue indefinitely at its highest velocity. (iii) Maximum value is that beyond which the process comes to stop.
