Question

Birth defects and prenatal diagnosis ​

Answer 1

Answer:

Birth defects are structural changes present at birth that can affect almost any part or parts of the body (e.g., heart, brain, foot). They may affect how the body looks, works, or both. Birth defects can vary from mild to severe.

prenatal diagnosis: examples include heart defects, cleft lip or cleft palate, and spina bifida. Teratogenic disorders occur when the baby is exposed to substances during pregnancy that cause abnormalities, otherwise known as “teratogens.” Babies are very sensitive in the first trimester, when all of the organs are developing.
