Reproductive systems are based on the goal of creating offspring. Both the male and female reproductive systems, although fueled by a similar goal, have different components and structures. Both systems are very complex in their own ways, which makes it important to understand how each of the systems and their various processes work. Knowing the processes and components of the male and female reproductive systems will help all people in their lives, sooner or later. It is important to understand how our individual bodies work and how life is produced. The female reproductive system is made up of 9 parts. The sex cell for the female reproductive system is called an egg or ovum. The egg spends its life dormant in the ovary until it is released. The egg has 23 chromosomes inside it. The ovaries have two goals: to create and house eggs and to release the female sex hormones, estrogen and progesterone. The fallopian tubes are the place through which the egg travels to reach the uterus. The fallopian tubes contain tiny hair-like structures called cilia; the cilia allow the mobility of the egg. The fallopian tube is about the size of 2 hairs and is the site where ectopic pregnancies occur. The process by which the egg is released from the ovaries through the fallopian tubes is called ovulation. Ovulation occurs on the 14th day of the menstrual cycle. The uterus is where the egg goes after passing through the fallopian tubes. The developing baby is held and nourished in the womb. When the uterus is empty, it is about the size of a fist but expands as the embryo begins to develop. The endometrium is the lining of the uterine wall. It is used to protect the fetus. When the egg is not fertilized, menstruation has… half of the paper… the purpose is to clean the urethra of harmful bacteria and other substances before ejaculation. The penis, not composed of muscle or bone, is the next step for sperm. Its three main purposes are to transport urine, transport semen, and provide sensation. Inside the penis is the urethra. The functions of the urethra are to transport urine from the bladder to the outside of the body and ejaculate sperm during sexual intercourse. The tip of the penis is called the scrotum, and its three main functions are to act as a thermometer for the testicles, protect and hold the testicles, and provide various sensations. Overall, the male and female reproductive systems are important parts of our lives. Knowing them better can help us understand how to do certain things, such as prevent pregnancy. The more you know yourself, the more you understand others.
