In this live Gr 12 Life Sciences show we take a look at Processes in Human Reproduction. In this lesson we state that the menstrual cycle include the uterine and ovarian cycles. We describe the events in the ovarian and uterine cycles. We describe the hormonal control of the menstrual cycle. We describe the negative-feedback mechanism. We define copulation and fertilisation. We state where and how fertilisation occurs. We define implantation. We state the role of oestrogen and progesterone in maintaining pregnancy. We identify and state the functions of the parts of the developing embryo/foetus. Finally, we name the three stages of the natural birth process.
