Fetal and maternal physiology and ultrasound diagnosis

Abstract

Fetal developmental potential is determined at the moment of conception by genetic inheritance. However, this development is modulated by environmental factors. It is important to recognize that both, the mother and the fetus, actively participate in the maintenance of the physiological intrauterine environment. Unfortunately, the fetus is not entirely protected from harmful influences of the external factors. By altering the intrauterine environment, these factors can have a long-term effect on fetal health.
