In today's society, there are approximately seven billion humans on Earth, but these individuals did not appear by magic. For this to be possible, a sperm must accompany an egg, also called fertilization, to create a human being. Sperm and eggs are created through meiosis, which is nuclear division that ends in haploid cells that create mature gametes. Once completed, the sperm begins as a round cell and then generates a tail that gives it the mobility to swim up to an egg and fertilize it. Fertilization is achievable with both the female reproductive system and the male reproductive system. Overall, this system is an amalgam of functional organs and hormones that cooperate together to generate life. The female reproductive system is subject to creating the female sex hormone and the egg, receiving the egg from the sperm, and providing a location where the fertilized egg can develop. The male reproductive system is responsible for reproducing the male sex hormone, producing sperm, and delivering them to the female's reproductive system. Once females reach puberty, hormones allow the reproductive system to create ova or mature eggs. In the female body, two white ovaries are present in the uterus, one is located on the left side and the other on the right side. Inside the ovaries are the eggs and when the female reaches puberty, her eggs will begin to mature each month. Once developed, they will be passed out and enter the fallopian tube. As it travels through the tube, it is likely to be fertilized by a sperm during coitus. If fertilized, the egg will adhere to the front of the uterus and ultimately create a follicle then a zygote...... middle of paper...... the sperm must become sperm. To do this, the glands of the vas deferens, such as the prostate, bulbourethral glands and seminal glands, will be secreted in order to support and promote the gamete. Together, sperm is produced, which is a milky, white male reproductive fluid. As coitus progresses, a man becomes sexually aroused and ejaculates, which moves the sperm to the urethra and from there it will be inserted into the vagina and then into the fallopian tube to be fertilized. Overall, both reproductive systems work. as well as their unique structures to create life on Earth. Female and male organs allow for a fusion of genetic material, which allows for genetic variation. Since everyone begins life as a zygote, the cell has all the instructions necessary to create a unique human being. Obviously the system is responsible for its creation.
