The pupil is a "hole" in the iris which allows light to enter the eye.

Stand in front of a mirror and gaze deeply into your eyes. In the centre of your eyeball, you will see a small opening. This opening, called the pupil, is made larger or smaller by the coloured iris around it. It is the iris, be it blue, green, brown or black, that gives our eyes their characteristic colour. In bright light, the iris muscles expand so that the opening of the pupil becomes smaller and less light passes into the eyeball. In dim light, the pupil is opened wider and more light is let in. When you come indoors to a dark interior from bright sunlight, the pupil is narrowed.

However, within seconds the iris adjusts, like the diaphragm of a camera, to make the pupil larger and let in more light. If you flash torchlight towards your eye, as you face a mirror, you will be able to see the narrowing light of the pupil.

A 'pupil' is where a young man puts his 'WHO WHO' when he meets and falls in love with his young lady friend...and then that's how babies are made.  Where did you think they came from?? Storkovia?
