Definition
A fetus is a stage in human development that follows the embryonic stage. It begins from the ninth week after fertilization until birth.
Analogy
If we continue with our building analogy, think of a fetus as being at the construction phase. The blueprint has been laid out (the embryonic stage), and now everything is starting to take shape - walls are going up, rooms are being defined etc.
