"Biologically" Speaking...

They say we won’t be here without our parents, and I thank them because of what they have done to us. But because of my Biology class, it opened up my mind to the real world and made me learned that we must also extend our gratitude to both the sperm and egg cells of our father and mother. In addition and I am sure that everyone knows it, and this is the process where all living organisms produce offspring called reproduction.

As an introduction, males have their male reproductive system, which has penis, scrotum, vas deferens, and most especially the chief male reproductive organs, the two testes. And on the other hand, females have their female reproductive system, which has the oviduct, urethra, vagina and if males have testes, well females have their ovary. Males have their hormone testosterone. Testosterone is the principal male sex hormone and is responsible for making the whole male system active. While females have a hormone called follicle-stimulating hormone. This hormone is responsible for stimulating the ovarian follicle to grow and reach maturity. This hormone of females is only one among many other hormones in the female system.

And now let’s proceed to the process.

All of our mother won’t be pregnant if it isn’t her fertile days, so there must be ovulation—when a follicle matures, its wall ruptures, setting the ovum free. Ovulation takes place in both ovaries alternatively. While the ovum enters the opening end of the oviduct, sperms are introduced into our very own female system, they travel upward until they reach the lower portion of the oviduct. During that time, many sperms are surrounding the ovum. Sperm is believed that it has enzymes, which are responsible for dissolving the thick outer layer of the ovum, and when one sperm penetrated the outer layer of the ovum and then fertilize it. Then the uniting of sex cells or gametes is taking place and there will be fertilization. After fertilization, zygote undergoes cell division as it goes down and resulting mass of these undifferentiated cells is embryo. With the help of the umbilical cord—structure which connects the embryo to the mother; and the placenta—part of the uterus to which the umbilical cord is attached; the embryo can get rid of waste materials such as urea. And that embryo is I, you and all of us. My mother told me that I stayed in her womb for more or less than 9 months, (which is the normal period for a baby to stay in a mother’s womb). She added that she really had a hard time releasing me from her womb because I am big and it took the doctor more or less 3 hours just for getting me out. After giving birth, my mother felt asleep and she wake up the next day. The doctor told my mother that I was a normal and healthy baby girl. My mom gave me breast feeding for more than 1 and a half years and she gave me vitamins for my growth and mental strength.

And I am pretty sure that your mother and father really took care of you. Because there is no parent that can’t resist his or her kids.
