shuter speed, aperture and ISO speed essentially work together like a balancing act to get the same thing (proper exposure).
think of it this way : to get a properly exposed image, you need to capture as much light in such a way that you expose the sensor with just the right amount (aperture), long enough (shutter speed) to register with the sensor (ISO speed) properly.
