Developing areas with rapid cell division are the most vulnerable areas to malformation caused by environmental teratogens Membranes, amniotic fluid, yolk sac, umbilical cord, placenta Fetus: 9 weeks until pregnancy ends - Refinement of structure until fetus reaches viability Teratogens - Answer -Something that is going to affect the anatomical or the physiological development of the embryo during the embryonic stage and/or the fetus during the fetal stage Need assistance on Online classes, Exams & Assignments?
