Good video though not bad on the term basal plate, I know it is technically correct though can be confused with the embryonic neural tube.
this is the best explaination out there! thanks so much
I like the language and terminology. The whole process kinda gets me imagine every bit of it and get there to feel the placenta. Oops :-P
Thank you!! Is it beneficial to keep the baby attached to the placenta and just allow the umbilical cord to fall off on its own?
Great Explanation!

Wonderful
It was really helpful!!
Women didn't have a uterus in the 1950s. My mom told me a baby was in its mom stomach. I wondered why it wasn't digested. Stomachs digest food, don't they? Be glad you're in a new century. The 50s were a bit confusing.
Thank you so much!!!
Lovely stuff cheers!!!
awesome thanks
Awesome.
Awesome 🌹🌹✨
thank you!!
In the video seems like placenta belongs to both mom and fetus. But in the faculty lesson professor told us "Placenta only belongs to fetus". Which one is true?
Are uterine veins and umbilical veins synonyms?
A big big biiiiiiiiiiiiig thumbs up!!!!!
thanks alot
U rocked it
Can't thank you enough
Thank you :)
Thanks a bunch
Hey guys,
I'm proud to make recommendation of Mr Brooks to whom I met when I was preparing for my NCLEX RN exams. Thanks to him I finally celebrated after several trials. I'll forever be grateful to him. You can contact Mr Brooks via text or whatsapp: +12404085402. I'm overwhelmed with joy. He has got everything you need to succeed in your exams be it RN or LPN and you will see reasons to celebrate the way I do.
the best thanks :)

Is there any name for that pool of blood?
So placenta is basically thick endometrium lining of uterus?
habib nagori no!
without khan academy (esp this guy) i would've paid more attention in my lectures.
HOLY COW that BABY!!! is HUUUUUGE LOOOL
you are using blue for the arteries which usually represents deoxygenated blood so do the veins carry the oxygenated blood to the fetus in the placenta?
Yes. The fetal circulation is exactly the opposite of the mom's circulation. And so the arteries carries the de-O2 blood and the vein carries the O2 blood. 😊👍😇
+Ashley Thomas Yes, the way I remember it is that Arteries go Away from the heart and Veins go towards the heart; the same as adult circulation. The difference is that the baby is incapable of oxygenating its own blood so needs mom to bring O2 blood to its heart via umbilical vein. It also needs to rid of De-O2 blood and waste products which is does through the umbilical artery.
Conclusion: Umbilical vein: O2 blood
Umbilical artery: deoxygenated blood
And the baby does not have that much room in the womb, as it grows it takes up all the room.
Subhan'allah ❤️❤️🌼
Our great god ❤️ Allah the creator 🤍
where are the decidua capsularis and the decidua parietalis?
Capsularis is between the blastocyst and the uterine cavity. And the parietalis is lining the rest of the wall of the uterus.
Cool
what is heomochorial placenta?
Sourav De it means that chorion layer of placenta is in direct contact of maternal blood.( Haemo- blood)
