Life Stages
Embryo 2-6 weeks the embryonic stage of development, from 2 to 8 weeks after fertilization, cells differentiate and arrange themselves in the proper locations to form the major organ systems. The embryo shown here is about 5 to 6 weeks old and less than 3 cm long. The organ systems and extern body structures are not fully developed. Fetal period 9 weeks to birth
The fetal stage of development begins at 9 weeks after fertilization and continues until birth. During this time, the fetus grows, and internal and external body structures continue to develop. This fetus is about 16 weeks old and about 16 cm long. From the ninth week on, the developing offspring is a fetus during the fetal period, structures formed during the embryonic period grow and mature. The placenta continues to nourish the fetus until birth. During this time, the length of the fetus increases from about 3 cm to around 50 cm. The fetal period usually ends after 40 weeks, with the birth of an infant weighing 3 to 4 kilograms (6.5 to 9 pounds).

Common Illness Pre-eclampsia is a problem that occurs in some women during pregnancy. Blood
