A fetus develops in such a way that the type II cells of the lungs never develop, resulting in no production of surfactant in th
g100num [7]

Due to the high surface tension, the lungs remain crushed and you will not be able to breathe first.

During fertilization, the sperm and egg combine in one of the fallopian tubes to form a zygote. The zygote then descends the fallopian tube into a morula. Upon reaching the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the inner wall of the uterus. This is a process called implantation.

The prenatal development process occurs in three major stages. The first two weeks after conception are called the germination period, the third to eighth weeks are called the fetal period, and the period from the ninth week to birth is called the fetal period.
