In placental mammals, the umbilical cord (also called the birth cord or funiculus umbilicalis) is the connecting cord from the developing embryo or fetus to the placenta. During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and (in humans) normally contains two arteries (the umbilical arteries) and one vein (the umbilical vein), buried within Wharton's jelly. The umbilical vein supplies the fetus with oxygenated, nutrient-rich blood from the placenta. Conversely, the fetal heart pumps deoxygenated, nutrient-depleted blood through the umbilical arteries back to the placenta.

Famous quotes containing the word cord:
“Ah! How neatly tied, in these people, is the umbilical cord of morality! Since they left their mothers they have never sinned, have they? They are apostles, they are the descendants of priests; one can only wonder from what source they draw their indignation, and above all how much they have pocketed to do this, and in any case what it has done for them.”
—Antonin Artaud (1896–1948)
