  1. Reproduction System By: Azra Krdzalic

  2. What is it? And are there different types? Reproduction — the process by which organisms make more organisms like themselves — is one of the things that set living things apart from nonliving matter. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. There are two types of reproduction systems that are different in shape and style. There is the male and female systems.

  3. http://kidshealth.org/teen/interactive/mrs_it.html Male reproductive system? What's that exactly? The sexual organs of the male are partially visible. The penis and the scrotum are on the outer while the prostate gland and seminal vesicles (these are small tubes which link the male reproductive system together) are inside. The reproductive system in the male body is designed to allow the manufacture, storage and transfer of sperm.

  4. But wait… what’s the female reproduction system? • The female reproductive system enables a woman to: • produce eggs (ova) • have sexual intercourse • protect and nourish the fertilized egg until it is fully developed • give birth http://kidshealth.org/teen/interactive/mrs_it.html The female, unlike the male, does not manufacture the sex cells. A girl baby is born with about 60,000 of these cells, which are contained in sac-like depressions in the ovaries. Each of these cells may have the potential to mature for fertilization, but in actuality, only about 400 ripen during the woman's lifetime.

  5. What happens when we reproduce? Sperm "swim" up from the vagina through the cervix and uterus to meet the egg in the fallopian tube. About a week after the sperm fertilizes the egg, the fertilized egg has become a multi-celled blastocyst. The blastocyst travels to the uterus and gains its nutrients from the blood that has been building up. After approximately 8 weeks, the blastocyst/embryo is about the size of an adult's thumb, but almost all of its parts — the brain and nerves, the heart and blood, the stomach and intestines, and the muscles and skin — have formed. When the baby is ready for birth, its head presses on the cervix, which begins to relax and widen to get ready for the baby to pass into and through the vagina. The mucus that has formed a plug in the cervix loosens, and with amniotic fluid, comes out through the vagina when the mother's water breaks. That’s when the walls expand and the child comes out.

  6. Weird but cool facts • Pregnancy lasts an average of 280 days — about 9 months • It takes only one sperm to fertilize the egg • 0.05 and 0.2 fluid ounces (1.5 to 6.0 milliliters) of semen is deposited into the vagina. Between 75 and 900 million sperm are in this small amount of semen • The external part of the female reproductive organs is called the vulva, which means covering • The vagina, which is approximately two and one-half to four inches long, has muscular walls that are supplied with numerous blood vessels • the epididymis and the testicles hang in a pouch-like structure outside the pelvis called the scrotum
