Feedback:
The period of the fetus lasts from the beginning of the ninth week after fertilization through birth, which is usually at about the end of the 40th week of pregnancy. This is a period of increasing growth, differentiation, and functional development of the tissues that appeared during the embryonic period. At about 20 weeks of gestation, the fetus becomes viable (having some chance of life outside the uterus).
