This edition: The Beginnings: Prenatal Development and Birth
This lesson follows the experiences of an expectant family through the prenatal process to the live birth of their second child. During this journey, students learn about the three trimesters of pregnancy and the developmental expectations associated with each trimester. Students also learn about the germinal, embryonic, and fetal periods of prenatal development. These divisions provide an orderly context in which to understand the environmental and genetic influences on the developing infant. The video lesson examines risk factors, or teratogens, that often influence the success or failure of conception and later the delivery of a healthy baby. It also discusses ways to reduce these risks and ensure that expectant mothers receive the proper prenatal care.
