umbilical arteries การใช้

• Branches of the umbilical arteries carry embryonic blood to the villi.
• Chorionic arteries branch off the umbilical artery, and supply the capillaries of the chorionic villi.
• Closure of the umbilical artery by vasoconstriction consists of multiple constrictions which increase in number and degree with time.
• Obstetric ultrasonography can also use doppler technique on key vessels such as the umbilical artery can detect abnormal flow.
• The adrenal glands often appear as small oval discs pressed against the esophageal and duodenal atresia, and a single umbilical artery.
• Blood is carried to the villi by the paired umbilical arteries, which branch into chorionic arteries and enter the chorionic villi as cotyledon arteries.
• It is heard because of the rush of blood through the umbilical arteries of the foetus, and is therefore synchronous with the foetal pulse.
• Therefore although the pO2 in the uterine arteries is low, the foetal umbilical arteries ( which are deoxygenated ) can still get oxygenated from them.
• However, this naming convention reflects the fact that the umbilical vein carries blood towards the fetus's heart, while the umbilical arteries carry blood away.
• Additional factors that are important in HSC migration during this period are Integrins, umbilical arteries and the allantois, in which HSCs and endothelial cells are colocalized.
• The umbilical arteries are actually the latter of the internal iliac arteries ( anterior division of ) that supply the hind limbs with blood and nutrients in the fetus.
• In one of the studies, researchers inserted a catheter through the babies'umbilical arteries and into their aortas, and then submerged their feet in ice water.
• The umbilical vein, umbilical arteries, ductus venosus and ductus arteriosus are not needed for life in air and in time these vessels become ligaments ( embryonic remnants ).
• The dorsal aortae give branches to the yolk-sac, and are continued backward through the body-stalk as the umbilical arteries to the villi of the chorion.
• On multiple occasions, people have changed this section of text to state that the umbilical arteries carry oxygenated blood to the fetus, and that the umbilical vein carries deoxygenateay.
• The two umbilical arteries branch from the internal iliac arteries, and pass on either side of the urinary bladder into the umbilical cord, completing the circuit back to the placenta.
• Part of each umbilical artery closes up ( degenerating into what are known as the medial umbilical ligaments ), while the remaining sections are retained as part of the circulatory system.
• On multiple occasions, people have changed this section of text to state that the umbilical arteries carry oxygenated blood to the fetus, and that the umbilical vein carries deoxygenated blood away.
• THIS IS INCORRECT . The article as it stands is correct, as the nomenclature reflects the fact that the umbilical arteries carry blood from the fetal heart, while the umbilical vein carries blood towards it.
• In the fetus, the normal range differs based on which umbilical vessel is sampled ( umbilical vein pH is normally 7.25 to 7.45; umbilical artery pH is normally 7.18 to 7.38 ).
