During pregnancy, the umbilical cord is a vital structure that supports fetal growth and survival. It serves as the connection between the fetus and the placenta, enabling the transfer of oxygen and nutrients while facilitating the removal of waste products. In uncomplicated pregnancies, the umbilical cord develops and functions normally. Routine antenatal care includes assessment of the cord and placental circulation, which helps ensure appropriate fetal wellbeing. Understanding its function can provide reassurance and improve confidence during pregnancy.
