Placental transfer is a difficult question what actually gets crossed.
The placenta had stopped working.
all placental mammals like us. But there are two other groups. One of those groups is the monotremes. These are mammals that still lay eggs. They are very primitive mammals. And these are
And that placenta is the richest source of stem cells.
Turns out you can think of the placenta as the 3D printer that manufactures the baby.
technologically advanced societies can get through the placental wall and get these into the child into these
Maybe she had an injection to make the placenta come out.
don't want to talk about uh they showed me the placenta I thought it was an Italian rice dish and when I saw it it
like us. Placentals are the ones that can give live birth to well-developed babies that can develop for a long time in their mother's boobs. So dogs and cats and bats and wells and elephants,
mammals. Placental mammals are the dominant ones today. But we see the roots of these three major groups back in the Cretaceous period. Now what we see in the fossil record is that those
So we're looking at the early evolution of the placental mammal brain.
We have the world's largest bank of placentas .
They're pluripotent because they can make every cell in the body except for the placenta , in fact.
But I think it's pretty well established that these do cross the placental barrier near the fetus.
And things that potentially could have been spotted during my pregnancy, like my placenta failing, which could potentially have stopped
That's one of the things that defines mammals in general, particularly placental mammals, is our giant heads and giant brains.
cell count up and active um all of that can't apply because we know what will and will not cross the placental barrier
Sadly enough, toddlers have three times the level in their bodies compared to adults, because they get their mothers level through the placenta .
And this is the first sound, the first music, which is engraved in our brain; those vibrations of the placenta .
So imagine this is an ancestral mammal and one of them invents milk and the other one invents the placenta and we have to decide
mammals mammals that we have that other mammals have. In the world today, there are three major types of mammals. We are placental mammals. And about 95% of all mammals are placental mammals
the first 10 million years or so of evolution after the asteroid, there were mammals. There were lots of new mammals. These mammals were getting bigger. It was mostly placental mammals,
charge. It was their ancestors. It was this whole host of archaic placental mammals, things like Pantodonts and Taeniodonts and Tillodonts and Condylarths. These mammals names mean nothing
The problem is, the stress hormones of the mom, some of them actually can cross over the placental barrier and go into the baby's bloodstream,
but they give it very slowly, they know what has-- what will and will not cross the placental barrier.
