The Reproductive System
Jacqueline Cilliers - 7
The reproductive system or genital system is a system of sex organs within an organism, male and female, which work together for the purpose of sexual reproduction. Scientists argue that the reproductive system is among the most important systems in the entire body because without the ability to reproduce, a species dies.
The Female Reproductive System
The female reproductive system produces the female egg cells necessary for reproduction, called the ova or oocytes. The system is designed to transport the ova to the site of fertilization. The fertilization of an egg by a sperm, normally occurs in the fallopian tubes.The fallopian tubes connect the ovaries to the uterus. The uterus is like a small room for the baby to grow. The cervix is the narrow entryway in between the vagina and uterus. The vagina is like a tube and can grow wider to deliver a baby that has finished growing inside the uterus. The hymen covers the opening of the vagina and can be broken with sexual contact or when using a tampon for the first time. The breasts are a pair of milk-producing organs of the female reproductive system located on the left and right sides of the anterior thoracic (chest) region. Each breast projects outward from the anterior of the chest as a mass of skin-covered soft tissue. At the tip of the breast is a small cylindrical projection of erectile tissue called the nipple. The nipple is bordered by a ring of thickened, bumpy skin called the areola.
The Male Reproductive System
The male reproductive system includes the penis, scrotum and testicles, as well as various internal accessory organs, such as the prostate gland and the seminal vesicles, which produce most of the fluid that makes up the ejaculate. The glans, also called the head of the penis, is covered with a loose layer of skin called foreskin. This skin is sometimes removed in a procedure called circumcision. The testicles are the male gonads responsible for the production of sperm and testosterone. The scrotum is a sac-like organ made of skin and muscles that houses the testes. The seminal vesicles are a pair of lumpy exocrine glands that store and produce some of the liquid portion of semen. The ejaculatory duct contains the ducts from the seminal vesicles. The prostate is a walnut-sized exocrine gland that borders the inferior end of the urinary bladder and surrounds the urethra which is a muscular tube 8 to 10 inches long.
The reproductive systems of both female and male come together with a process called sex. This is where the males sperm fertilizes the females egg and after a 9 month period of time (pregnancy) the baby is ready to come out of the uterus.
