What is cord tissue?
The term "cord tissue" refers to the rest of the umbilical cord, other than the blood. A normal umbilical cord contains one artery, two veins, an outer skin, and it is filled with a gelatinous material called Wharton’s Jelly. Umbilical cords can vary widely in length, but the average cord is about 61 cm (24 inches) long and weighs 40 gm.
