Question

Exposure of a developing embryo or fetus to certain environmental factors can damage the developing organism or even cause death. What impact can Maternal Diseases have on a delivering mother?

A. can cause birth defects
B. infant brain damage
C. acquired immune deficiency syndrome
D. can produce defects by crossing the placental barrier

Answer 1

Maternal diseases such as exposure to alcohol, infections like rubella and toxoplasmosis, and teratogens including radiation can severely affect fetal development, leading to a wide range of birth defects, developmental delays, and health issues.

Step-by-step explanation:

Maternal diseases can have a significant impact on the developing embryo or fetus, potentially leading to various complications for the child. For instance, exposure to alcohol can lead to fetal alcohol spectrum disorders, which encompass a range of physical, cognitive, and behavioral issues. Similarly, infections such as rubella can cause severe consequences like fetal death or birth defects including heart defects, microcephaly, and cognitive deficits. Toxoplasmosis is another maternal disease that can cross the placenta and cause damage to the central nervous system of the fetus, leading to conditions such as mental , deafness, or blindness.

Other factors like nutritional deficiencies and exposure to teratogens like radiation and certain medications can also pose risks to fetal development. These exposures may lead to skeletal abnormalities, congenital disorders, or even spontaneous abortion. Hence, it is essential for expectant mothers to receive proper prenatal care, including screening for infectious diseases and maintaining a balanced diet.
