Related to umbilical vein: right umbilical vein

left um·bil·i·cal vein

the vein that returns the blood from the placenta to the fetus; traversing the umbilical cord, it enters the fetal body at the umbilicus and then passes into the liver, where it is joined by the portal vein; its blood then flows by way of the ductus venosus and the inferior vena cava to the right atrium.
Synonym(s): vena umbilicalis [TA]

umbilical vein

one of three embryonic vessels in the umbilical cord. It functions to return the blood from the placenta and fuses to form a single vein in the umbilical cord.

left um·bil·i·cal vein

(left ŭm-bil'i-kăl vān)
Returns the blood from the placenta to the embryo; traversing the umbilical cord, it enters the embryo body at the umbilicus and then passes into the liver, where it is joined by the portal vein; its blood then flows by way of the ductus venosus and the inferior vena cava to the right atrium; the right umbilical vein disappears during the seventh week.
Synonym(s): vena umbilicalis [TA] , umbilical vein.

umbilical

pertaining to the umbilicus.

umbilical abscess
see urachal abscess.
umbilical clamp
used in calves and foals for the closed method of herniorrhaphy. Consists of two lightweight bars that can be screwed together very tightly. The herniated gut is evacuated from the hernia and the clamp applied to as much of the hernial pouch as can be included. The tissue beyond the clamp sloughs and the clamp can be removed.
umbilical cord
see umbilical cord.
umbilical cord infection
umbilical diverticulum
an evagination of the bowel wall at the vestigial point of attachment of the yolk sac. Called also Meckel's diverticulum.
umbilical gas gangrene
umbilicus infected with Clostridium septicum, C. oedematiens.
umbilical hemorrhage
a specific syndrome in newborn piglets. Bleeding from fleshy navel, also from ear notching, causes fatal anemia. The cause is unknown.
umbilical hernia
protrusion of abdominal contents through the abdominal wall at the umbilicus, the defect in the abdominal wall and protruding intestine being covered with skin and subcutaneous tissue. Occurs sporadically in all species and inherited in cattle and some breeds of dogs. Soft swelling at umbilicus is reducible into the abdomen through a palpable ring. May accompany omphalitis.

umbilical hernia strangulation
the intestinal loop in the hernia becomes incarcerated with its lumen occluded and its blood supply compromised.
umbilical inflammation
umbilical occlusion
as when the umbilical cord is trapped between the fetus and the wall of the birth canal, causing loss of the fetal blood supply.
umbilical sinus
created by persistence of only the distal end of the intraembryonic allantoic stalk at the umbilicus.
umbilical tape
cotton tape, about 0.5 inch, with two selvedge edges. Used to tie off an umbilicus in calves and foals.
umbilical vein
one of a pair of veins which return oxygenated blood from the placenta through the umbilical cord to the ductus venosus and thence to the heart.
umbilical vein infection
umbilical vein abscess
residual after subsidence of acute omphalophlebitis.

A recent study reported in the Neural Regeneration Research showed that the stress decrease at 7 200 seconds was similar between the middle cerebral artery and fetal umbilical vein specimens, regardless of initial stress of 18.
The result of this fetal circulation arrangement is that blood sampled from the umbilical arteries will be deoxygenated blood and reflect the metabolic state of the fetus and blood sampled from the umbilical vein will be oxygenated blood from the placenta reflecting the functional aspects of placental gas exchange.
