The Reproductive System is very important, because it allows for reproduction of the human species.
Female Reproductive System:
Vagina: This is the female sex organ. The vagina is also known as the "birth canal." It also serves as a passageway for menstrual blood during menstruation.
Uterus: The uterus is an organ that contains two parts the cervix and the corpus. The cervix is the part of the uterus that opens to the vagina, and the corpus is used as a place for the fetus to develop and the egg to grow.
Ovaries: The ovaries store the eggs (ovum) and releases them when a women is menstruating.
Fallopian Tubes: The Fallopian Tubes serve as a connection between the ovaries and the uterus. The Fallopian Tubes allow for eggs to travel from the ovaries to the uterus.
Male Reproductive System:
Penis: This is the male organ used in sexual intercourse. The penis helps remove waste fluids from the male body, and inserts sperm in the female to produce offspring.
Testicles: The testicles are responsible for producing and storing sperm, as well as producing hormones.
Scrotum: The scrotum functions as a sac that holds and supports the testes outside of the body. It also helps control the climate, allowing sperm to grow at a temperature lower than the temp of the internal body.
Epididymis: This stores and discharges the sperm produced in the testes.
Vas Deferens: This is a long muscular tube that carries fully developed sperm to the urethra when awaiting ejaculation.
Urethra: This helps move urine and semen out of the body.
Seminal Vesicles: These are two small sac like glands on either side of the male bladder. They add nutrient fluid which help the movement of semen during the ejaculation.
Prostate Gland: This organ surrounds the urethra of males. There is a muscular part, which controls the release of urine but also another part which secretes fluid that makes up part of the semen enhancing its fertility.
Life of a Sperm Cell:
The testes contain coiled structures the, "seminiferous tubes," which is where sperm production takes place. The immature sperm cells travel from there to the epididymis. Here the sperm is matured and stored. Once they are mature enough they travel through the Vas Deferens. Smooth muscle contractions propel the sperm forward. The sperm now arrives at the ampulla (widest part of the Vas Deferns) and then into the ejaculatory ducts. A liquid secretion from the seminal vesicles mixes with the sperm. The sperm now passes through the prostate gland, and is projected toward the urethra. Finally the sperm is ejected out of the urethra at the end of the penis.
Life of an Egg Cell:
The egg is first released from the ovaries, and then travels to the fallopian tubes. It can now be fertilized by a sperm cell or remain unfertilized. No matter if it is fertilized or not it moves through the fallopian tubes into the uterus. If it is fertilized, the egg will implant on the lining of the wall of the uterus and begin to grow. If the egg is not fertilized, the lining will shed. The lining and the egg, will exit the body through the cervix and vagina during a woman's period.
