Your videos are great, but I suggest if you made a brief conclusion of the whole video or this small lecture on one or two written slides that would be so beneficial for us to study
This is both hilarious and also super helpful
I am just speechless very nice and creative 👌 😍 😊 🙂
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 video is Amazzzzzzzzzzzzzzzzzzzzing
I love you with all my fore brain sir🥰🥰🥰
Cool
A big big biiiiiiiiiiiiig thumbs up!!!!!
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?
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.
Can't thank you enough
It look like a happy face
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
best
Are the fetal vessels contain in the villi? If blood doesn’t mix why is anti D given
lmao that umbilical cord looked like that clown ham slices hahaha
That baby is tooo big hahahahh. Great video. Thank you :)
the first drawing killed me 😂 the baby looks well past 40 weeks
Looks like a kid
So care package gets delivered within 8-9 months?
Is there any name for that pool of blood?
Are uterine veins and umbilical veins synonyms?
❤❤❤❤
marry me!!! best explanation ever
liaalixx exactly lol!!
hola
what is heomochorial placenta?
Sourav De it means that chorion layer of placenta is in direct contact of maternal blood.( Haemo- blood)
So placenta is basically thick endometrium lining of uterus?
habib nagori no!
sentiotrophoblaste to be accurate
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?
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.
Hii
And the baby does not have that much room in the womb, as it grows it takes up all the room.
HOLY COW that BABY!!! is HUUUUUGE LOOOL
Subhan'allah ❤️❤️🌼
Our great god ❤️ Allah the creator 🤍
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
Fetus in the uterus ... i m weak
without khan academy (esp this guy) i would've paid more attention in my lectures.
nice video.
The eyes are A It’s a :-) mouth
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.
im sorry but....this voicemakes me dizzy like seriously so deep
Oh
God place you
