    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.

      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.

  • @ashleythomas3187
    @ashleythomas3187 8 років тому

    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?

    • @emphasis3340
      @emphasis3340 8 років тому +5

      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. 😊👍😇

    • @jkaur0326
      @jkaur0326 8 років тому +1

      +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

    • @noursaied3532
      @noursaied3532 8 років тому

      Capsularis is between the blastocyst and the uterine cavity. And the parietalis is lining the rest of the wall of the uterus.
