WebA developing fetus is most vulnerable to birth defects during the embryo stage when organs are developing. For example, substance or chemical exposure can cause the greatest damage to a fetus between two and 10 weeks after conception. Medical science has identified the cause of about 30% of birth defects. WebFor example, a cell that is going to be part of a lung has to perform a different function than a cell that will be part of the stomach. But before cells can differentiate, the embryo must go through a process called gastrulation. During gastrulation, an embryo’s cells split into separate layers called germ layers. WebEmbryogenesis is the process by which an embryo develops into a foetus. It begins when an ovum and sperm meet and fertilization occurs. The fertilization results in the formation of a zygote. The zygote divides mitotically multiple times without any significant growth and cellular differentiation, leading to the development of an embryo. brewery\\u0027s u4
