How Does The Umbilical Cord Work?
|
I am interested in knowing how the umbilical cord works. I know that it carries food an oxygen from the placenta, but that is about it. How does the placenta make manufacture the food? How does the baby's body know that it doesn't need the umbilical cord anymore as soon as its born?

the umbilical cord will bring the oxigen and the food for your baby and it comes into the blood that runs in the umbilical cord, so everything that you eat the nutrients and vitamins goes there by your blood, and the baby inside the tummy does not breath by his lungs that are closed by the time he is inside your belly, so after he born his lungs open and he is ready to don[t need the umbilical cord anymore. Amazing how our body knows everything that we need at all stages in our life.

The umbilical cord is the life-line that attaches the placenta to the fetus. The umbilical cord is made up of three blood vessels: two smaller arteries which carry blood to the placenta and a larger vein which returns blood to the fetus. It can grow to be 60 cm long, allowing the baby enough cord to safely move around without causing damage to the cord or the placenta.

After the baby is born, the cord is cut (something the baby's father may wish to do); the remaining section will heal and form the baby's belly button.
During pregnancy you may find out that the umbilical cord is in a knot, or is wrapped around a part of your baby's body. This is common and cannot be prevented, and it usually does not pose any threats to the baby.

Umbilical cord(3-4cm long) plays a crucial role in the development of baby.It delivers oxygen and nutrition and carries away waste. It is attached to the placenta on one end and baby's belly on the other. Inside the baby, it joins up with specialized blood vessels that connect to the heart and liver.umbilical cord usually has three blood vessels, which spiral around each other. The larger blood vessel carries oxygen and nutrients from the placenta to the baby, and the two smaller vessels carry back the baby's waste products.Oxygen is provided for the fetus throughout the entire pregnancy by the mother, through the placenta. Following birth the placenta continues to provide oxygen for approximately 5 minutes while blood pumps, to and fro, through the umbilical cord.placenta serves the baby as lungs, liver, kidneys and intestines until babies birth. The placenta also performs some of the functions of a hormone gland.It exchanges carbon dioxide from the baby's bloodstream for oxygen from the mother's. After delivery, the umbilical cord will be clamped and cut, since the baby no longer needs his mother's help in getting food and air. (Cutting the cord hurts neither the mother nor the baby.) Once blood stops flowing through the umbilical cord, the placenta detaches from the uterus
