The only conduit between the placenta and the growing embryo or fetus is the umbilical cord. It is also called as funiculus umbilicalis or birth cord. In humans at the time of prenatal development the umbilical cord becomes the part of the fetus both genetically and physiologically. It generally contains one vein called as the umbilical vein and two arteries called umbilical arteries both are buried in Wharton’s jelly. From the placenta the nutrient rich oxygenated blood is supplied to the fetus via umbilical vein. In the fetal heart starts to pump the nutrient exhausted and oxygen less blood to the placenta via umbilical artery. After the delivery of the baby if it takes more than 15 seconds for the cord to clamp then it is called as delayed cord clamping as delayed clamping takes place between 25 seconds to 5 minutes. This results is increasing the blood level of the infant because the late clamping allows the blood to flow to the infant until the cord clamps completely.
