Key Concepts

Teratogens

Teratogens are agents that can disturb the development of an embryo or fetus. They include chemicals, biological agents, or physical agents that may cause birth defects, malformations, or other developmental disorders if exposure occurs during critical periods of prenatal development.

Placental Barrier

The placental barrier is a semi-permeable structure that facilitates the exchange of nutrients and oxygen between the mother and fetus, while also allowing certain substances, including some harmful chemicals and drugs, to pass through. This passage can lead to exposure of the developing fetus to potential teratogens.

Developmental Toxicology

Developmental toxicology is the field of study that investigates the adverse effects of chemical and physical agents on the developing organism. It focuses on understanding how exposure to various substances during prenatal stages can lead to abnormalities in structure or function, which may result in birth defects or long-term health issues.
