they are passed to the fetus and cause imbalanced compounds that effect DNA
Absolutely YES! Substances of good/bad can be transported from what is inhale by the mother to the fetus by the process of "blood flow from the mother to the fetus" or entering the umbilical cord to the fetus .
blood flow from the mother to the fetus
yes.....it can
The fetus is not in the bowel, so, no. If the fetus has been borne, then still, no.
No, they are safe.
Not likely.
It may not harm the fetus but will harm YOU for sure. Say NO to 'drugs'.
The placenta is not an effective barrier against harmful substances because it is designed to facilitate the exchange of nutrients and waste between the mother and fetus. Many toxins, drugs, and infections can cross the placental membrane due to their small size or lipid-soluble nature. Additionally, certain pathogens can exploit mechanisms within the placenta to gain access to the fetal environment. As a result, substances that may harm the fetus can often bypass the protective functions of the placenta.
No
trauma, toxins, and malnutrition.
microorganisms can harm animals by infecting them, releasing toxins inside of animals when consumed, or causing malnutrition.
Theoretically it is risky to the fetus if you smell the bleaching. But practically it will be taken up by body tissue and it will not harm your fetus.
