Reproductive System, Part 4 - Pregnancy & Development: Crash Course Anatomy & Physiology #43
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!
