Answer :
Critical period
Critical period is the time of
development in which the body can be very sensitive to damage that may be
caused by the administration of drugs, alcohol or other harmful conditions during
pregnancy. At the critical period, all
of the baby’s organs start forming and functioning. The developing fetus
experiences rapid cell differentiation during this period.
Critical period is the term that is given to the time period during which irreversible damage to the fetus may occur from specific events, such as malnutrition or exposure to toxins. During pregnancy, each part of the fetus body forms at a specific time, during which the body can be very sensitive to damage caused by medications, alcohol or other harmful exposures, and this is the critical period of development for a particular body part.
