How come campbells and raven john dont have anything about fetal ciiculation - ductus arteriosus, foreman ovale, etc. ? Whats a good source for this? Thanks

Both books are not sufficient with respect to DNA technology either.

I guess it's just their way of seperating the men from the boys....

Na, DNA tech is good in campbells, but i dont understand where is info on fetal resp which i know for certain is tested on the DAT.

no one cares about your DAT score either.

I don't have a DAT score yet. That's probably why ;p ..........😀

Fetal circulation is easy:

ductus venosus: it bypasses the liver and blood goes straight to heart

foramen ovale: connects right atrium to left atrium, bypassing the lungs

ductus arteriosus: connects pulmonary artery to aorta, bypassing lungs


also dont forget that with the placenta, the circulation is kinda wierd like with the heart:

umbilical artery: carries deoxygenated blood from fetus to placenta

umbilical vein: carries oxygenated blood from placenta to fetus

Also:

After birth: resistance in pulmonary blood vessels decreases causing an increased blood flow to lungs. When the umbilical blood flow stops, blood pressure in the inferior vena cava decreases causing a decrease in pressure in right atrium.

In contrast, left arterial pressure increases due to increased blood flow to lungs.

Foramen ovale closes and ductus arteriosis constricts. Adult hemoglobin is produced.

Also good to know, erythroblastosis fetalis

Rh incompatability: occurs only when mother is Rh neg and her baby is Rh pos, and it affects the second born infant..so she has to have 1 Rh pos baby, then another one later on for this to occur

I had a question on it, and they asked what the Rh + or - was for mother and child so basically know mother Rh - , baby Rh+

I think I covered the important stuff, others can expand if I left anything out.

Wow, thank you so much. We do not need to know more detail? What textbook are you using? From what I hear the DAT focuses on developmental bio.

Campbells 7th edition

It has developmental bio in it also

chapterr 47 and also 21
