Question

In the human umbilical cord are there 2 arteries and 1 vein or 2 vein and 1 arteritis?

Answer 1

Hint: Umbilical cord is a tube that connects the baby to the mother’s body during pregnancy it has three blood vessels which carry food and oxygen to the placenta.

Complete answer:
The cord is considered a baby supply line because it supplies blood back and forth to the baby. It delivers nutrients and oxygen and removes waste products. It begins to form after 5 weeks after conception.
Arteries are blood vessels that are responsible for carrying oxygen rich blood from the heart to the body. veins are responsible for carrying deoxygenated blood from the body to the heart for oxygenation. These are two main types of blood vessels found in humans.
In humans most cords have one vein and two arteries veins are responsible for getting the oxygenated blood and other materials out of the Placenta and arteries are responsible to provide nutrients and oxygen to the placenta. in some cases, there are only two vessels a single artery and a single vein.

Note:
The umbilical cord forms after 4 weeks of pregnancy and usually grows about 22 inches long. In some cases, only a single artery is present; this happens in 1 in 100 it is known as singleton pregnancy.
