How is zodiac related to constellations?

The zodiac is the group of constellations where the Sun passes, in its yearly movement (this yearly movement is really the reflection of Earth's movement around the Sun). The "classical" Zodiac has 12 constellations, but the way constellations are organized today, the Sun actually passes through 13 constellations.
