When a pregnant woman ingests toxins such as alcohol the embryo is put at risk because?

When a pregnant woman ingests toxins such as alcohol, the embryo is put at risk because these substances can cross the placenta and reach the developing fetus. The placenta is a specialized organ that forms during pregnancy and allows for the exchange of nutrients, oxygen, and waste products between the mother and the fetus. However, certain substances, including alcohol, can also pass through the placenta and enter the fetal circulation.

Alcohol is a known teratogen, which means it can cause birth defects when consumed during pregnancy. Alcohol can interfere with the normal development of the fetus, leading to a range of physical, mental, and behavioral problems. Some of the potential effects of alcohol on the fetus include:

- Fetal alcohol syndrome (FAS): FAS is a group of birth defects that can occur when a woman drinks alcohol during pregnancy. FAS can cause a range of physical and mental problems, including growth retardation, facial abnormalities, heart defects, intellectual disabilities, and behavioral problems.

- Alcohol-related neurodevelopmental disorders (ARND): ARNDs are a group of conditions that can occur when a woman drinks alcohol during pregnancy, even if she does not meet the criteria for FAS. ARNDs can cause a range of problems, including learning disabilities, attention deficit hyperactivity disorder (ADHD), and other behavioral problems.

- Miscarriage: Alcohol consumption during pregnancy can increase the risk of miscarriage, especially if consumed heavily.

To protect the developing fetus, it is recommended that women avoid alcohol consumption during pregnancy. If you are pregnant or planning to become pregnant, it is important to abstain from alcohol to reduce the risk of potential harm to your child.
