During fetal life which is responsible for shunting a majority of blood flow of the umbilical vein directly into the IVC
A. portal vein
B. ductus arteriosus
C. ductus venosus
D. umbilical vein
Fetal circulation blood becomes oxygenated in
A. Lungs
B. Liver
C. Placenta
D. Umbilical vein
Primary function of the ductus venosus
Primary function of the ductus venosus is to carry oxygenated blood from the umbilical vein to the inferior vena cava and, ultimately, the left heart for systemic circulation.
Portal sinus supplies oxygenated blood to the liver itself.
Morison’s pouch
Morison’s pouch – a potential space between the visceral surface of the liver and the right kidney. This is the deepest part of the peritoneal cavity when supine
Morison’s pouch -Pathological abdominal fluid such as blood or ascites is most likely to collect in this region in a bedridden patient.
Doppler during the first trimester is a beneficial screening tool
Researchers have noted that decreased or abnormal blood flow through the ductus venosus during the first trimester has links with aneuploidies such as trisomy and Turner syndrome.
Therefore, Doppler during the first trimester is a beneficial screening tool for these conditions.
