    Study Notes

    The Reproductive System

    • The primary purpose of the reproductive system is to produce sex cells (gametes) and ensure the continuation of the species through sexual reproduction.

    Female Reproductive System

    • Ovaries:
      • Produce ova (egg cells) and release them during ovulation
      • Located in the lower abdomen
      • Each ovary contains thousands of follicles, each housing an immature egg
      • Produce female sex hormones, such as estrogen and progesterone
    • Uterus:
      • Hollow, muscular organ located in the pelvis
      • Has a thick lining called the endometrium and muscular walls
      • Where a fertilized egg implants and develops into a fetus during pregnancy
    • Fallopian Tubes:
      • Connect the ovaries to the uterus
      • During ovulation, an egg is released from an ovary and travels through a fallopian tube towards the uterus
      • Fertilization typically occurs within the fallopian tubes
    • Vagina:
      • Muscular canal that extends from the cervix to the outside of the body
      • Serves as the passage through which menstrual blood leaves the body
      • Receives the penis during sexual intercourse
      • The birth canal through which a baby is delivered

    Male Reproductive System

    • Testes:
      • Produce sperm cells and the male sex hormone testosterone
      • Located in the scrotum, a pouch of skin that hangs outside the male body between the legs
    • Scrotum:
      • Houses the testes and regulates their temperature, keeping them slightly cooler than the body's core temperature
      • Essential for sperm production
    • Penis:
      • External organ used for urination and sexual intercourse
      • Contains erectile tissue that can fill with blood, causing an erection
      • During ejaculation, sperm are expelled through the penis
    • Epididymis:
      • Long, coiled tube located at the back of each testis
      • Where sperm mature and are stored before ejaculation
    • Vas Deferens:
      • Ducts that transport mature sperm from the epididymis to the urethra in preparation for ejaculation
    • Urethra:
      • Tube that carries urine from the bladder to the outside of the body
      • In males, it also carries semen during ejaculation

    Main Processes in the Reproductive System

    • Ovulation:
      • Process during which an ovary releases a mature egg
      • Typically occurs around the midpoint of the menstrual cycle
    • Fertilization:
      • Combines a sperm cell from the male with an egg cell from the female
      • Usually happens in the fallopian tubes
    • Implantation:
      • The fertilized egg, now called a zygote, implants itself into the lining of the uterus
      • Continues to develop into an embryo and later into a fetus
    • Menstruation:
      • If fertilization does not occur, the lining of the uterus is shed through the vagina
      • Part of the menstrual cycle
    • Ejaculation:
      • Release of semen, which contains sperm, from the penis
      • Occurs during sexual climax and is necessary for the sperm to reach the female reproductive system

    Health Issues Involving the Reproductive System

    • Infertility:
      • Affects approximately 10% of heterosexual couples
      • Makes it difficult or impossible to conceive a child
      • Can affect either the male or female reproductive systems
    • Foetal Alcohol Syndrome (FAS):
      • Occurs when a pregnant woman consumes alcohol
      • Causes serious birth defects in the unborn baby
      • Lifelong and irreversible effects
    • Sexually Transmitted Diseases (STDs):
      • Infections passed from one person to another through sexual contact
      • Can have serious health consequences if left untreated
      • Include HIV/AIDS, syphilis, gonorrhea, chlamydia, and herpes
    • Endometriosis:
      • Condition in which tissue similar to the lining inside the uterus grows outside the uterus
      • Causes pain, irregular bleeding, and infertility
      • Treatment may involve medication, hormone therapy, or surgery
    • Prostate Issues:
      • Common in older men
      • Include benign prostatic hyperplasia (BPH) and prostate cancer
      • BPH is a non-cancerous enlargement of the prostate gland that can cause urinary problems
      • Prostate cancer is a serious condition that requires medical treatment

      • Makes it difficult or impossible to conceive a child
      • Can affect either the male or female reproductive systems
    • Foetal Alcohol Syndrome (FAS):
      • Occurs when a pregnant woman consumes alcohol
      • Causes serious birth defects in the unborn baby
      • Lifelong and irreversible effects
    • Sexually Transmitted Diseases (STDs):
      • Infections passed from one person to another through sexual contact
      • Can have serious health consequences if left untreated
      • Include HIV/AIDS, syphilis, gonorrhea, chlamydia, and herpes
    • Endometriosis:
      • Condition in which tissue similar to the lining inside the uterus grows outside the uterus
      • Causes pain, irregular bleeding, and infertility
      • Treatment may involve medication, hormone therapy, or surgery
    • Prostate Issues:
      • Common in older men
      • Include benign prostatic hyperplasia (BPH) and prostate cancer
      • BPH is a non-cancerous enlargement of the prostate gland that can cause urinary problems
      • Prostate cancer is a serious condition that requires medical treatment

    The Reproductive System

    • The primary purpose of the reproductive system is to produce sex cells (gametes) and ensure the continuation of the species through sexual reproduction.

    Female Reproductive System

    • Ovaries:
      • Produce ova (egg cells) and release them during ovulation
      • Located in the lower abdomen
      • Each ovary contains thousands of follicles, each housing an immature egg
      • Produce female sex hormones, such as estrogen and progesterone
    • Uterus:
      • Hollow, muscular organ located in the pelvis
      • Has a thick lining called the endometrium and muscular walls
      • Where a fertilized egg implants and develops into a fetus during pregnancy
    • Fallopian Tubes:
      • Connect the ovaries to the uterus
      • During ovulation, an egg is released from an ovary and travels through a fallopian tube towards the uterus
      • Fertilization typically occurs within the fallopian tubes
    • Vagina:
      • Muscular canal that extends from the cervix to the outside of the body
      • Serves as the passage through which menstrual blood leaves the body
      • Receives the penis during sexual intercourse
      • The birth canal through which a baby is delivered

    Male Reproductive System

    • Testes:
      • Produce sperm cells and the male sex hormone testosterone
      • Located in the scrotum, a pouch of skin that hangs outside the male body between the legs
    • Scrotum:
      • Houses the testes and regulates their temperature, keeping them slightly cooler than the body's core temperature
      • Essential for sperm production
    • Penis:
      • External organ used for urination and sexual intercourse
      • Contains erectile tissue that can fill with blood, causing an erection
      • During ejaculation, sperm are expelled through the penis
    • Epididymis:
      • Long, coiled tube located at the back of each testis
      • Where sperm mature and are stored before ejaculation
    • Vas Deferens:
      • Ducts that transport mature sperm from the epididymis to the urethra in preparation for ejaculation
    • Urethra:
      • Tube that carries urine from the bladder to the outside of the body
      • In males, it also carries semen during ejaculation

    Main Processes in the Reproductive System

    • Ovulation:
      • Process during which an ovary releases a mature egg
      • Typically occurs around the midpoint of the menstrual cycle
    • Fertilization:
      • Combines a sperm cell from the male with an egg cell from the female
      • Usually happens in the fallopian tubes
    • Implantation:
      • The fertilized egg, now called a zygote, implants itself into the lining of the uterus
      • Continues to develop into an embryo and later into a fetus
    • Menstruation:
      • If fertilization does not occur, the lining of the uterus is shed through the vagina
      • Part of the menstrual cycle
    • Ejaculation:
      • Release of semen, which contains sperm, from the penis
      • Occurs during sexual climax and is necessary for the sperm to reach the female reproductive system
