The ligamentum venosum, also known as Arantius' ligament, [1] is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis. It may be continuous with the round ligament of liver. It is invested by the peritoneal folds of the lesser omentum within a ...
The fetal circulatory system includes three shunts to divert blood from undeveloped and partially functioning organs, as well as blood supply to and from the placenta. In humans, the circulatory system is different before and after birth. The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical ...
The ductus venosus (red) connects the umbilical vein to the inferior vena cava. The liver and the veins in connection with it, of a human embryo, twenty-four or twenty-five days old, as seen from the ventral surface. In the fetus, the ductus venosus (Arantius' duct after Julius Caesar Aranzi [1]) shunts a portion of umbilical vein blood flow ...
The liver is divided into four lobes. This image shows the large right lobe and a smaller left lobe separated by the falciform ligament. 1: Right lobe of liver 2: Left lobe of liver 3: Quadrate lobe of liver 4: Round ligament of liver 5: Falciform ligament 6: Caudate lobe of liver 7: Inferior vena cava 8: Common bile duct 9: Hepatic artery 10 ...
The ligamentum arteriosum plays a role in major trauma. It fixes the aorta in place during abrupt motions, consequently potentially resulting in a ruptured aorta. Such ruptures are very rare. If the ductus arteriosus fails to close after birth, a condition known as patent ductus arteriosus can develop. This is a fairly common birth defect.
A ligament is the fibrous connective tissue that connects bones to other bones. It is also known as articular ligament, articular larua, [1] fibrous ligament, or true ligament. Other ligaments in the body include the: Peritoneal ligament: a fold of peritoneum or other membranes. Fetal remnant ligament: the remnants of a fetal tubular structure.
arteriosus_by_E5.11.1.8.1.0.4 E5.11.1.8.1.0.4. FMA. 70301. Anatomical terminology. [edit on Wikidata] The truncus arteriosus is a structure that is present during embryonic development. [clarification needed] It is an arterial trunk that originates from both ventricles of the heart that later divides into the aorta and the pulmonary trunk. [1]
In placental mammals, the umbilical cord (also called the navel string, [1] birth cord or funiculus umbilicalis) is a conduit between the developing embryo or fetus and the placenta. During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and (in humans) normally contains two arteries (the umbilical ...
