Question | Answer |
Umbilical cord contains | 2 arteries and one vien |
Carry waste products away from fetus to the mother through the placenta | arteries |
Carries nutrients and oxygen to the fetus from the mother through the placenta | vein |
Fetus does not purify its blood in the | liver |
All chambers in the fetal heart have | equal pressure |
Oxygenated blood from placenta (mother) enter the fetus through the | Umbilical vein |
Path of blood to IVC takes one of two paths | 50% travels through the liver and into IVC and the rest bypasses the liver |
50% of blood bypasses the liver by going through the | Ductus venosus and than IVC |
Is located close to the umbilical vein and regulates blood entering the IVC through ductus venosus | splincter |
Overloading the fetal heart when the sphincter is CLOSED, more blood goes into the | PV and enters the IVC |
When the sphincer is OPEN, blood flows into | the ductus venosus and enters the IVC |
If the volume of venous flow is high the sphincter | closes and the blood has a longer route to IVC, this prevents overloading of heart |
The IVC contains what two types of blood when it enters the right atrium | Oxygenated and Deoxygenated blood |
Blood from umbilical vein | Oxygenated |
Blood from lower part of the fetal body | Deoxygenated` |
