Document Summary
Chapter 11: human development across the life span. Prenatal period- extends from conception (formation of a zygote) to birth: 9 months. Placenta- allows 02 and nutrients pass into the fetus and waste back to mom"s body. 2nd stage- embryonic (2w-2month), where most of the vital organs and bodily system begins to form, making it a period of great vulnerability and miscarriages are most likely to occur. Interferences in the development during this phase leads to birth defects. 3rd stage- fetal (2m-birth), where organs continue to develop and gradually function and then it reaches the age of viability meaning the baby can survive at this age (22-26 weeks). Severe maternal malnutrition can increase the risk of birth complications and neurological defects for the newborn because a developing fetus needs a variety of essential nutrients. Low birth weight linked to increased risk of heart disease and diabetes in adulthood.
