We've reached the grand finale of our four part series on human reproduction: BABIES! Today Hank walks you through the stages of pregnancy, beginning with how a zygote develops into blastomeres to a morula to a blastocyst and finally to an embryo and a fetus. He also explains some of the amazing anatomical changes that take place in the mother, and the hormonal sequence of events that lead to labor. Pssst. we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!

I was introduced to your videos last semester in A&P1 and have watched you since! But this semester I was introduced to your history lessons AND I saw you in some art assignment videos! You've changed a lot in the years! Good for you, can't wait to see what you teach next; )

All of this smacks of intelligent design & not of mindless evolution. Intelligent design smacks of an Intelligent Designer or Creator. (Those who are unable to see this must be blind)
