This is because the umbilical cord plays a crucial role in providing necessary nutrients, oxygen, and removing waste products from the developing baby. As the pregnancy progresses, the blood vessels in the umbilical cord mature and shrink in diameter, leading to a decrease in its overall size compared to the early stages. The larger size of the umbilical cord in early pregnancy facilitates efficient nutrient exchange between the mother and the developing fetus, supporting the baby's growth and development.
