venosus การใช้

• There are two other fetal shunts, the ductus venosus and the foramen ovale.
• The sinus venosus connects to the fetal circulation.
• In a trial, " Dardanus venosus " showed a preference for large anemones over small ones.
• A sinus venosus ASD that involves the superior vena cava makes up 2 to 3 % of all interatrial communication.
• In teleosts, with their vestigial sinus venosus, the main centre of coordination is, instead, in the atrium.
• Pacemaker cells develop in the primitive atrium and the sinus venosus to form the sinoatrial node and the atrioventricular node respectively.
• Individuals with a sinus venosus ASD exhibit a left axis deviation of the P wave ( not the QRS complex ).
• The vessels draining the plexus into the sinus venosus are termed the venae revehentes, and form the future hepatic veins.
• Ultimately the left vena revehens no longer communicates directly with the sinus venosus, but opens into the right vena revehens.
• "Dardanus venosus " often has the sea anemone " Calliactis tricolor " attached to its shell.
• Indeed, since the sinus venosus is incorporated into the right atrium in amniotes, it is likely homologous with the SA node.
• The tubular heart quickly differentiates into the truncus arteriosus, bulbus cordis, primitive ventricle, primitive atrium, and the sinus venosus.
• The smaller vessel, now called the ductus venosus, diverges away from the liver and joins with the inferior vena cava ."
• "Calliactis tricolor " is often found attached to a gastropod shell occupied by another hermit crab, " Dardanus venosus ".
• The human venous system develops mainly from the vitelline veins, the umbilical veins and the cardinal veins, all of which empty into the sinus venosus.
• The second branch ( known as the ductus venosus ) bypasses the liver and flows into the inferior vena cava, which carries blood towards the heart.
• From the inflow to the outflow, it consists of sinus venosus, primitive atrium, the primitive ventricle, the bulbus cordis, and truncus arteriosus.
• The life cycle of " Dardanus venosus " has been little studied but the eggs are probably brooded attached to the female's abdomen.
• In these animals, the muscles of the heart are relatively continuous and the sinus venosus coordinates the beat which passes in a wave through the remaining chambers.
• The ductus venosus shows a delayed closure in preterm infants, with no significant correlation to the closure of the ductus arteriosus or the condition of the infant.
