biology (3rd quarter science)

• Female and male reproductive system - internal and external organs in both female and male that work together for the purpose of procreating
• Producing sperm and releasing testosterone - function of male reproductive system
• Testes - producing sperm
• Scrotum - sac of skin that holds the testes
• Penis - deposits sperm into vagina during mating
• Vas deferens - carries sperm from testes to urethra
• Urethra - carriers sperm and urine out of the body
• Glands - provide liquids in which sperm can swim
• Semi vesicle - a fluid that makes up the most of the components of the semen
• Prostrate gland - a slightly alkaline milky fluid that a discharge as part of the semen
• Bulbourethral - a thick and clear mucus that lubricates and neutralizes the only trace of acidic urine in the urethra
• Penis - a lubricant, smegma produced under the prepuce on the penis
• Sperm - carry either female or male chromosomes
• Acrosome - the head of the sperm Contains enzymes
• Head of sperm - Carries the genetic material
• Midpiece of sperm - supplies energy
• Tail or flagellum - provides motility
• Testes - sperm - epididymis - vas deferens - semi vesicle - ejaculatory duct - prostrate gland - urethra - expulsion from the body - THE SPERM PATHWAY
• release egg cells

  Produces sex hormones such as progesterone and estrogen

  Provide an environment for a fertilized egg to develop during pregnancy - FUNCTIONS of female reproductive system
• Ovary - produces egg cells
• Oviduct - serves as passage way of eggs from the ovary to the uterus
• Uterus - site of egg implantation and where the fertilized egg develops
• Fallopian tube - where egg cell and sperm meet to fertilize
• Vagina - receives the male penis during mating
• 3 layers of uterus wall

  Endometrium

  Myometrium

  Perimetrium
• Perimetrium - the outside layer of uterus
• Myometrium - the muscular inside layer of uterus
• Endometrium - the mocus membrane lining
• 12 - 24 hours - life of egg cell
• Follicle - small sack of glands containing the egg cell
• Menarche - first day of menstruation
• Menopause - stops of menstruation
• Puberty - when a child's body begins to develop as they become an adult.

  Girls develop BREAST and starts their PERIOD

  Boys develop DEEPER VOICE and FACIAL HAIR starts to appear
• Hormones - regulating and complex chemical substances secreted by endocrine glands
• Pituitary gland - serves as communication and sending signals to pituitary gland as hormones pass through blood stream
• Hypothalamus and pituitary gland - control function of both ovaries and testes

  Keep reproductive system property functioning
• Menstrual cycle - hormonal process that occurs in a woman's body each month to prepare for a possible pregnancy
• Menstruation (1-5 days)

  Follicle phase (6-14 days)

  Ovulation phase (14th day)

  Lutheal phase - (15-28 day) - 4 PHASES OF MENSTRUAL CYCLE
• Menstruation (1-5day) - uterine lining shed
• Ovulation phase (14th day) - egg cell is released
