Umbilical cord (UC) is the main connection between mother and the growing fetus. It acts as the career of nutrients helps in exchange of gases etc. The length of the UC is approximately 20 inches. UC is of main interest for researchers in the recent times. The umbilical cord blood (UCB) has been fruitful source of Stem Cells. UCB helps in the reformation of different blood components. The umbilical cord provides the growing embryo with oxygen, nutrient-rich blood from the placenta. In the same manner, the fetal heart pumps deoxygenated, nutrient-depleted blood through the umbilical arteries back to the placenta.
