  • Paul Andersen starts with a brief description of asexual and sexual reproduction. He explains how meiosis ensures variation in the next generation. He describes the important structures in the male and female reproductive system. He explains how the menstrual cycle ensure the success of the released ovum. He also shows how a zygote becomes a blastula, gastrula, embryo and fetus.

    I watched your videos for AP Biology, college General Biology, and college Genetics. I am now watching your videos to help me study for the biology portion of the MCATs. Thank you so much you have helped me for several years and always made science even more fun and interesting! You are such an inspiration!!!

    Great video, however the cervix sits below the uterus and at the apex of the vaginal canal. Just to clarify.

    No need for the correction at 3:01 Mr Andersen the prostate gland does secrete alkaline fluid to neutralize acidity in urethra (due to urine) as well as the seminal fluid itself and the acidity of the vagina.

  • @valeriafernandez3967
    @valeriafernandez3967 Před 11 lety +10

    From what I have been studying, during ovulation a secondary oocyte is released, not an ovum. Ovum is a term used only once the sperm has penetrated.

    • @mirandahardy7474
      @mirandahardy7474 Před 3 lety

      in biology we learned that an ovum is just a mature egg... which is capable of being fertilized. It doesnt mean its already been fertilized.

    Hi! There is an error. He shows the cervix being at the opening of the vagina towards to the outside of the body, but it should be located above the vagina and below the uterus.

  • @xiaonvhai
    @xiaonvhai Před 11 lety

    At 2:57, you said the glands are neutralizing the pH inside the "vagina," I think you meant to say "vas deferens"?
    By the way, I'm actually using your videos to help me study for the MCAT (in addition to other review books). Thanks so much!

    • @amiraleu7823
      @amiraleu7823 Před 2 lety

      He is right, inside the vagina is very acidic, so germs can hardly grow. However, it is not sperm-friendly, thus those secretions work as chemical buffers to safeguard those sperm to meet the egg for fertilization.

    • @StephJ0seph
