SCIENCE

• Chromosomes


  contain genetic information which carries unique inherited traits such as skin color or hair color.
• 23


  How many chromosomes are there in a regular body cell
• 46


  How many chromosomes are there when the egg and sperm cells meet
• Haploid


  has 23 chromosomes
• Diploid


  has 46 chromosomes
• Egg and Sperm Cells


  two sex cells
• Male Reproductive System


  produces sperm cells and delivers them inside the female reproductive system
• Acrosome


  it stores the enzymes needed to penetrate an egg cell during fertilization.

  it is also a cap of the sperm cell
• Head


  it is made up of a nucleus covered by an acrosome, which stores the enzymes needed to penetrate an egg cell during fertilization

  it also contains acrosome, centriole and nucleus
• Midpiece


  it contains mitochondria that supply the energy needed to propel the sperm through the female tract
• Tail


  a powerful flagellum that enables the sperm cell to move
• Penis


  it is where the semen and urine leave the penis through the urethra
• Urethra


  the long tube that's allowing urine outside the body
• Testes/Testis


  responsible for making testosterone
• Testosterone


  the primary male sex hormone, and for producing sperm
• Scrotum


  it has a protective function including the maintenance of optimal temperatures for sperm survival and function
• Epididymis


  a long, coiled tube that rests on the backside of each testicle that transports and stores sperm cells that are produces in the testes
• Vas Deferens


  it transports mature sperm to the urethra in preparation for ejaculation
• Seminal Vesicle


  a pair of glands found in the male pelvis which function to produce many of the constituent ingredients of semen
• Prostate Gland


  produce fluid that nourishes and transports semen
• Bulbourethral Gland


  it produces a clear, slippery fluid that neutralizes the acidity of the urine residue in the urethra, helps to neutralize the acidity of the vagina, and provides some lubrication for the tip of the penis during intercourse
• Labia Majora


  in enclose and protect the other external reproductive organs
• Labia Minora


  they lie just inside the labia majora and surround the openings to the vagina and urethra
• Bartholin's Gland


  located next to the vaginal opening on each side and produce a fluid secretion
• Clitoris


  a small, sensitive protrusion that is comparable to the penis in males
• Vagina


  a canal that joins the cervix to the outside of the body

  also known as birth canal
• Uterus


  a hollow, pear-shaped organ that is the home to a developing fetus
• Cervix


  the lower part of the uterus that opens into the vagina
• Corpus


  the main body of the uterus that can easily expand to hold a developing baby
• Fallopian Tube


  a narrow tubes that are attached to the upper part of the uterus and serve as pathways for the ova to travel from the ovaries to the uterus
• Ovaries


  produces an egg cell to be fertilized by a sperm in the process of fertilization

  it is located inside the abdominal cavity located just slightly below the waist, with one ovary on each side of the body and just like the testes, it also produce hormones
• Estrogen


  one of the hormones of ovaries that triggers the development of secondary female characteristics such as the widening of the hips and the enlargement of the breasts

  it also stimulates egg development
• 400,000


  By the time a female reaches puberty, the number of egg cells would have gone to_
• Ova


  mature egg cells
• Female Reproductive Cycle


  the process of producing an ovum and readying the uterus to receive a fertilized ovum to begin pregnancy
• The Ovarian Cycle


  governs the preparation of endocrine tissues and release of eggs
• Follicular Phase


  begins when the anterior pituitary gland releases the gonadotropins follicle stimulating hormone and luteinizing hormone into the bloodstream
• Follicle-Stimulating Hormone

  FSH
• Luteinizing Hormone


  LH
• Luteal Phase


  luteinizing hormone causes the the cells of the ruptured follicle to grow, forming a corpus luteum, a mass of follicular cells that functions like an endocrine gland
