• vessels
  • Chorionic (plate) vessels are blood vessels, including both arteries and veins, that carry blood through the chorion in the fetoplacental circulation. (wikipedia.org)
  • The umbilical cord contains Wharton's jelly, a gelatinous substance made largely from mucopolysaccharides which protects the blood vessels inside. (wikipedia.org)
  • In absence of external interventions, the umbilical cord occludes physiologically shortly after birth, explained both by a swelling and collapse of Wharton's jelly in response to a reduction in temperature and by vasoconstriction of the blood vessels by smooth muscle contraction. (wikipedia.org)
  • spiral arteries
  • Spiral arteries in decidua are remodeled so that they become less convoluted and their diameter is increased. (wikipedia.org)
  • There is relatively high pressure as the maternal blood fills intervillous space through these spiral arteries bathes the fetal villi in blood, allowing an exchange of gases to take place. (wikipedia.org)
  • oxygen
  • The arteries are part of the circulatory system, which is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, the maintenance of optimum blood pH, and the circulation of proteins and cells of the immune system. (wikipedia.org)
  • The pulmonary artery carries blood from the heart to the lungs, where it receives oxygen. (wikipedia.org)
  • medial
  • The medial umbilical ligament (or cord of umbilical artery) is a paired structure found in human anatomy. (wikipedia.org)
  • It is on the deep surface of the anterior abdominal wall, and is covered by the medial umbilical folds (plicae umbilicales mediales). (wikipedia.org)

  • carries
  • Systemic arteries are the arteries (including the peripheral arteries), of the systemic circulation, which is the part of the cardiovascular system that carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart. (wikipedia.org)
  • ductus
  • In males, it may also give rise to the artery to the ductus deferens which can be supplied by the inferior vesical artery in some individuals. (wikipedia.org)
  • cords
  • Most cords have one vein and two arteries. (wikipedia.org)
  • They are used due to their low cost, and simple techniques for isolating them from umbilical cords, which are normally resected after childbirth. (wikipedia.org)
  • The artery in cords of preterm infants contracts more to angiotensin II and arachidonic acid and is more sensitive to oxytocin than in term ones. (wikipedia.org)
  • cardiac
  • In 11 (68.8%) of the 16 cases with cardiac defects the condition was readily diagnosable by evaluating the standard four-chamber view and the views of the great arteries. (slideshare.net)
  • The pressure in arteries varies during the cardiac cycle. (wikipedia.org)
  • infants
  • However, the groups did not differ in the numbers of infants who were small for gestational age, who had low Apgar scores or umbilical artery acidosis, and who required admission to the special care nursery. (biomedsearch.com)
  • Anatomy
  • The anatomy of arteries can be separated into gross anatomy, at the macroscopic level, and microanatomy, which must be studied with the aid of a microscope. (wikipedia.org)
  • normal
  • In about 75% of those cases, the baby is entirely normal and healthy and the missing artery isn't missed at all. (wikipedia.org)
