Why is the placenta not an effective barrier against substances that harm the fetus?
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.

Agar jelly can also absorb water and become softer over time, which may affect its barrier properties.
Uterine membrane transport substances between mother and embryo?
The uterine membrane, comprised of the placenta, facilitates the exchange of nutrients, oxygen, and waste products between the mother and embryo. This transport occurs through diffusion, active transport, and facilitated diffusion mechanisms. The placenta also acts as a barrier to prevent harmful substances from crossing between the maternal and fetal circulations.
What does the placents do?
The placenta is an organ that develops during pregnancy to provide nutrients and oxygen to the growing fetus. It also acts as a barrier to protect the fetus from harmful substances and helps remove waste products from the baby's bloodstream. After birth, the placenta is expelled from the mother's body.
What I the name of the organ where substances pass between the mothers and fetus blood?
The organ where substances pass between the mother's and fetus's blood is called the placenta. It facilitates the exchange of nutrients, gases, and waste products, ensuring that the developing fetus receives the necessary materials for growth while allowing waste to be removed. The placenta acts as a barrier to some harmful substances, providing a degree of protection to the fetus.
Is Tyvek an effective vapor barrier?

What ORGAN blocks entrance of many drugs because of a barrier similar to the blood brain barrier?
The placenta acts as a barrier to many drugs due to its structure and functions similar to the blood-brain barrier. It is designed to protect the developing fetus from harmful substances while allowing essential nutrients to pass through. This barrier prevents many drugs from crossing into the fetus's bloodstream during pregnancy.
