Reproductive System, Part 1 - Female Reproductive System: Crash Course Anatomy & Physiology #40

Рет қаралды 5,201,315

Күн бұрын

Human reproduction is complicated and important, and it's going to take a four-part series for us to cover it. Today, we're kicking that off with the female reproductive system, starting with how sex hormones affect oogenesis and ovulation, continuing through how the ovarian and menstrual cycles mature and release oocytes, and creating a comfy uterine environment for a fertilized egg.

There are many components to studying human anatomy. One place I discovered that successfully combines these is the Sebs Study Crammer (check it out on google) without a doubt the most incredible info that I've seen. Check out this interesting resource.

+Frank Schneider you make a valid point, but when you're a twelve y/o girl your mom already makes awkward conversations about puberty. Could you imagine asking her to buy you books on it? Or go to the library? Most of the books aimed at teens for pms are titled things like "EXPLORING YOUR CHANGING BODY," which is mortifying to read.

@frankschneider6156 8 жыл бұрын

Kirsten Joy You can get pretty much all of the basics from every introductory textbook on physiology. I mean I get your point, but if someone wants to know about a topic and doesn't look it up, that's highly irrational. Staying unknowledgeable just because of fuzzy emotions is imho a behavior that can not and should not be justified.

@diamcole 8 жыл бұрын

+Frank Schneider Chances are she attempted to do her own research on the matter and then turned to doctors for more in depth answers because she didn't fully understand. Nothing about that seems irrational when you consider that while yes, books are there for our own personal development, there are people who are deemed professionals and experts in their respective fields and it would be illogical to not seek them out because you've found a couple of books related to the topic in your local library and think that means you've now got all you need to solve the problem.

Cramping of those muscles can be really painful. My husband described one of my really bad cramp attacks as "That looks as painful as being kicked in the nuts". Can't know if it'll be mentioned in the next episode, but not all fertilized eggs succeed in drilling into the uterine wall. I believe, and please correct me if I'm wrong, that only about 1 in 4 is actually completely successful.
