The knowledge gained from working through the readings and activities in this microcredential will help you understand body systems’ function, regulation, and maintenance concerning the typical stages of embryonic and fetal development. You will explore genetic and environmental factors that may interfere with neonatal growth and development. This knowledge is helpful because it prepares you to reflect, research, and learn more about the factors that may impede a newborn’s successful transition to extrauterine life. This microcredential is the first in a series of three that corresponds to the unit of study 071 Applied Neonatal Physiology.
