Hi people, I am back now telling you guys about sexual reproduction.
Reproduction, as most people know, is giving birth. Reproduction is also split into 2 parts, mainly sexual reproduction and asexual reproduction. Today, I will only be focusing on sexual reproduction.
Having said much, I guess many of you are wondering, what is sexual reproduction.
Sexual reproduction in simpler terms means, a male and a female is needed to fertilise the ovum inside the female reproductive system. And today, I will only focus on Human Sexual Reproduction.
Just to add on for you guys to understand more about reproduction, I shall add on the definition of Asexual Reproduction.
Asexual Reproduction means that the reproduction process only involves a parent. An example of asexual reproduction will be algae.
Now I will move on to my focus of this post, Human reproduction.
Firstly, we have to know the major reproductive parts of both the male and the female. For the males, the reproductive are: Testes, Epididymis, Sperm duct, Seminal Vesicles, Prostate Gland, Cowper's glands and last but not least, the penis. As for the females, the reproductive parts are: Ovary, Oviduct, Vagina and the Uterus.
Now, after we know about the different parts of the human reproductive system, we would need to know the importance of the parts and what does the parts does.
Starting with the male reproductive system, I will firstly explain the testes. So why is the testes so important? The testes are the male's "sperm factory". The testes will constantly produce sperms that are used in the fertilization of the female's ovum. Without the testes, no sperm will be produced, therefore, reproduction will not take place.
Next, I will explain the importance of the epididymis. The epididymis acts as the "storage room" of the male's reproductive system. It temporary stores the sperm and the muscles in the epididymis will then contract and ejaculate sperms. Without the epididymis, sperms cannot be ejaculated, therefore, reproduction also cannot happen.
Next, I will explain the importance of the sperm duct. The sperm duct will transport the sperms from the epididymis to the urethra. Without the sperm duct, sperms also will not be ejaculated and therefore, reproduction also cannot happen.
Now I will move on to the glands. So we have the seminal vesicles, prostate glands and lastly the cowper's glands. So what does each of these glands do? The seminal vesicles will produce seminal fluid that are alkalic and will neutralise acidity in the female reproductive tract. The prostate glands will activate sperms and allow them to swim freely. Lastly, the cowper's glands will nourish the sperms with nutrients, allowing the sperms to be able to stay alive for a long period of time in the female reproductive system. Without these glands, the sperm will not be able to stay alive in the female's reproductive system long enough to fertilise the ovum.
Now I will move on to the last major part in the male reproductive system, the penis. The penis will erect when stimulated and will be the part that is inserted into the female's vagina and deposit the sperms. Without the penis, sperms will not be able to be deposited into the female's reproductive system.
Next, I will go on and explain to you guys the importance of each part in the female reproductive system. So let me start with the ovary. The ovary, similar to the testes of the male reproductive system, acts as a "factory". However, the difference between the ovary and the testes is that the ovary produces ovum MONTHLY. Another difference is that the testes produces sperms in large amounts at once, however the ovary produces the ovum ONE every monthly. Similar to the testes, without the ovaries, no ovum will be produced and therefore, reproduction cannot take place.
Next up, the oviduct. So why is the oviduct so important? The oviduct (a.k.a fallopian tube) will transport the ovum from the ovary to the uterus. The fertilisation of the ovum also takes place here. The fallopian tube is muscular and have strong contractions. Since the ovum is immobile due to its large size, the fallopian tube therefore serves as a "push". The strong contractions will move the ovum to the uterus. Without the fallopian tube, fertilisation cannot take place and the ovum also cannot be transported to the uterus. Hence, reproduction cannot happen.
Next will be the vagina. The vagina will be the place where the sperms are deposited during sexual intercourse. The vagina acts as a "connector" between the male reproductive system and the female reproductive system. Without the vagina, reproduction cannot happen as the sperms are unable to be deposited and the ovum in the female reproductive system cannot be fertilised.
Lastly, I will explain the importance of the uterus. The uterus (a.k.a womb) is the place where the fertilised ovum will develop to form a baby. It is muscular and elastic in order to push the foetus out when giving birth. Without the uterus, the fertilised ovum cannot develop and the foetus cannot be given birth.
In conclusion, this ends off my post on the importance of the major parts of the human reproductive system. There are still many parts that contributes to human reproduction, for example, STI and how it affects the foetus' growth and the human's reproductive system. Just a quick summary of this post, Human reproduction consists of the Male reproductive system, mainly made up of the testes, epididymis, sperm duct, different glands and the penis. There are still some parts that I did not state in this post (for example, the vas deferens) , but these are the major parts of the male reproductive system. Following it is the female reproductive system. The female reproductive system is mainly made up of the ovary, oviduct, vagina and the uterus. The female reproductive system is less complicated as compared to the male reproductive system in all.
Reflection:
I find that Biology, as compared to the other subjects, are much harder. There are many things that we have to study and most of the information cannot be get from just one source. Also the points that we have got to interact recently are strangers to us. For example, in our primary schools, we just got to know the basic parts in the human reproductive system. However, now, we have to learn so much more than most of us have expected and we have to get the information from different sources. However, the easy part of Biology is that we just have to memorise the points and we can score. Most of the stuffs, unlike physics and chemistry, are straightforward. As long we get the points correct, then we can score.
Thanks,
