The prenatal period in a person lasts on average how many days?

The prenatal period, human development can be divided into two periods. The first is embryonic. It lasts approximately 8-10 weeks. This period begins with the fertilization of the egg. The second period is fetal. It lasts until the birth itself. That is, this is the period from conception to childbirth, when the fetus is in the womb. On average, with normal fetal development, pregnancy lasts 39-40 weeks. This is 273 – 280 days. During the prenatal period, the baby develops and all internal systems are prepared for life in the natural environment.
