2023年7月24日 · The umbilical arteries carry deoxygenated blood from fetal circulation to the placenta. The two umbilical arteries converge together about at 5 mm from the insertion of the cord, forming a type of vascular connection called the Hyrtl's anastomosis.
Umbilical cord abnormalities: Prenatal diagnosis and management
2024年9月18日 · The umbilical cord contains two arteries and one vein surrounded by a gelatinous stroma (ie, Wharton's jelly) and covered by a single layer of amnion. The arteries carry deoxygenated blood from the fetus to the placenta, and the vein carries oxygenated blood from the placenta to the fetus.

2023年5月1日 · The umbilical arteries carry deoxygenated fetal blood toward the placenta for replenishment, and the umbilical vein carries newly oxygenated and nutrient-rich blood back to the fetus. When delivering oxygenated blood throughout the developing fetus, there are unique physiologic needs, supported by specific structures unique to the fetus which ...
Umbilical cord: Anatomical structure and function - Kenhub
2023年10月30日 · The umbilical cord is a bundle of blood vessels contained within a tubular sheath of amnion and consists of two paired umbilical arteries and one umbilical vein. The paired umbilical arteries function to carry deoxygenated blood from the fetus to the placenta while the umbilical vein carries oxygenated blood from the placenta to the fetus.
Umbilical artery - Structure, Location, Diagram, Function
2024年12月14日 · The umbilical artery is a vital vessel that primarily functions during fetal development, carrying deoxygenated blood from the fetus to the placenta. In the adult body, after birth, most of the umbilical artery becomes obliterated and forms the medial umbilical ligament, with only a portion remaining patent to supply the bladder.
