The timing and dosage of exposure to a teratogen are considered the two main factors that determine the extent of risk to a developing organism. The timing of exposure is important because different organs and systems develop at different times during gestation, and each has a critical period during which it is especially vulnerable to damage. The dosage of exposure is also important because the amount of a teratogen that enters the bloodstream can affect the severity of its effects on the developing organism.
