Fossa ovalis

4

Ligamentum arteriosum

5

What was Medial umbilical ligaments?

Umbilical arteries (taking deoxygenated blood to placenta)

6

What was Ligamentum teres

Umbilical vein (taking oxygenated blood to inferior vena cava at Liver and also hepatic portal)

7

What was ligamentum venosum

Ductus venosus (connecting umbilical vein to Inferior vena cava)

8

What was fossa ovalis

Foramen ovale (connecting to right atrium to left atrium)

9

What was ligamentum arteriosum

Ductus arteriosus (connecting pulmonary trunk directly to arch of aorta

10

fetal circulation oxygenated blood

Placenta -> Umbilical Vein -> Ductus Venosus (and Liver via hepatic portal) -> Inferior vena cava

11

Fetal circulation mixed blood

Inferior venacava -> Right atrium -> Right ventricle ->Pulmonary trunk -> Ductus arteriosus -> aorta -> systemic circulation -> umbilical arteries -. Placenta
