The umbilical artery is a paired artery (with one for each half of the body) that is found in the abdominal and pelvic regions. In the fetus, it extends into the umbilical cord. The umbilical arteries supply systemic arterial blood from the fetus to the placenta.

2023年10月30日 · The umbilical artery is a paired vessel that stems from the anterior division of the internal iliac artery. It runs anteromedially until it reaches the anterior abdominal wall. Then, it courses superiorly towards the umbilical ring, where it terminates.

In general, the more forward blood flow from the fetus to the placenta through the umbilical artery, the healthier the fetus. Table 2.1 summarizes measurements and vessel blood flow characteristics accessed by ultrasound and Doppler devices.

The umbilical artery passes anteromedially across the pelvis to the anterior abdominal wall. It then passes superiorly, along the inner surface of the anterior wall. Right and left arteries pass medially as they ascend to converge on the umbilicus.

2024年8月28日 · The umbilical artery gives rise to both a nonfunctional remnant of the fetal circulation and an active vessel giving supply to the bladder. In the adult, the obliterated area of the vessel is identifiable as the medial umbilical ligament and the patent segment is the superior vesical artery. Summary. origin: anterior division of the internal ...

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.

The umbilical artery (Latin: arteria umbilicalis) is a paired branch of the anterior trunk of the internal iliac artery that functions only in the time of the placental blood circulation. The umbilical arteries supply deoxygenated blood from the fetus to the placenta.

2023年4月10日 · This activity reviews the indications, technique of catheterizing the umbilical artery, potential complications associated with its presence, and highlights the role of an interprofessional team in managing neonates who undergo this procedure.

The umbilical artery in a neonate is a convenient site for monitoring arterial blood pressure, blood gases, and pH. It provides emergency access to an infant's circulation for restoration of blood volume and for administration of glucose and drugs. 114–117 Continuous monitoring of arterial oxygen saturation is also possible. 118

During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and normally contains 2 arteries—the umbilical arteries, and one vein—the umbilical vein, enveloped in Wharton’s jelly (a jelly-like intercellular substance of the umbilical cord).
