Reflection+of+science+topic+-+Sexual+Reproduction

====This was the first biology topic that we did this year. For this topic, we were being taught of the reproductive systems of both male and female humans, menstrual cycles. I learnt very much of the different organs in the reproductive system and their functions. For example, in the male reproductive system, there is scrotum that is outside the main body cavity so that it is at a lower temperature than the body for sperms to develop properly; there is testis, which is used produces male gametes, the sperm, and also male sex hormones such as testosterone. While in the female reproductive systems, there is the uterus, elastic muscular walls that are able to contract to push the fetus out during delivery; there is also the ovary, which is used to produce female gametes, the egg, and female sex hormones such as oestrogen and progesterone. All of these organs are very important in reproducing, without any of them, reproduction cannot take place. ====

====Then we learnt about the menstrual cycle. We learnt that menstrual cycle is a cycle of events that takes place in the female reproductive organs every month. But what happens during the cycle? To summarise it, in every month, the female reproductive system will ovulate to form egg to ready for reproduction. If the egg is not fertilised in the fertile period, the uterine lining will be broken down and being discharged. And that is menstruation. ====

====I feel that this topic is quite simple as memorising the different parts of reproductive systems and their functions would be sufficient to do well for this topic. However, menstrual cycle was not as easy because there are many different parts of the reproductive system that produce and inhibit different hormones that can cause different happening in the menstrual cycle. I had to understand every stage of the menstrual cycle well. For example, I understand that pituitary gland secretes follicle stimulating hormone that cause the development of follicle in the ovary. ====
