FLASH - Lesson Three, Reproductive System Option 2

Do Now Activity

• Task: In Google Classroom, list all the parts of the human reproductive system you remember.

Agenda

• Objectives:
  • Name parts of the human reproductive system.
  • Describe the path of an egg during the menstrual cycle.
  • Describe the path of sperm during ejaculation.
  • Recognize the wide range of normal anatomy.
  • Name the three main components of the sexual response.

Purpose

• Reproductive System:
  • Involves body parts for starting a pregnancy.
  • Involves egg and sperm joining through vaginal sex, sperm donation, or medical technology.
• Sexual Response System:
  • Involves body parts responsible for sexual feelings.

Reproduction

• Process where a single cell duplicates genetic material.
• Involves two special cells: sperm (male) and egg (female).
• Cells join through fertilization to form a zygote.
• Ensures perpetuation of the human species.

Male Reproductive System

• Parts: Cowper’s Gland, Epididymis, Penis, Prostate Gland, Scrotum, Seminal Vesicles, Testicle, Urethra, Vas Deferens.
  1. Testicles
     • Primary male sex organ.
     • Produce sperm and male hormones.
     • Contain coiled tubes for sperm production.
  2. Scrotum
     • Holds testes.
     • Regulates temperature for sperm production.
  3. Epididymis
     • Stores mature sperm.
  4. Vas Deferens
     • Long tubes for sperm travel.
  5. Seminal Vesicle
     • Adds seminal fluid to semen.
  6. Prostate Gland
     • Secretes fluid to activate sperm.
  7. Cowper’s Gland
     • Secretes mucus for lubrication.
  8. Urethra
     • Carries urine and semen outside the body.
  9. Penis
     • Contains sponge-like tissue that becomes erect during arousal.

Female Reproductive System

• Parts: Cervix, Glans of Clitoris, Fallopian Tubes, Fimbria, Ovary, Shaft of Clitoris, Uterus, Vagina.
  1. Ovary
     • Produces ova and female hormones.
  2. Fimbria
     • Guides ovum into fallopian tubes.
  3. Fallopian Tubes
     • Site of fertilization.
  4. Uterus
     • Where fertilized egg implants and fetus develops.
  5. Cervix
     • Connects vagina and uterus.
  6. Vagina
     • Passageway for menstrual fluid and childbirth.
  7. Glans and Shaft of Clitoris
     • Provides sensation.

Egg Lifetime

• Fetal life: 6-7 million eggs.
• Birth: ~1 million eggs.
• Puberty: ~300,000 eggs remain.
• Reproductive lifetime: 300-400 eggs ovulated.

Sexual Response System

• Components: Emotions, brain, hormones, senses, entire body.
• Aspects:
  1. Desire: Wanting sexual closeness.
  2. Arousal: Sexual excitement.
  3. Release: Reduction of sexual tension.

Homework

• Choose one of two assignments: Individual or Family.
• Review Questions:
  • Ovaries and testicles produce sex cells and hormones.
  • Sperm and egg are both sex cells needed for reproduction.
  • Fallopian tubes and vas deferens are pathways for egg and sperm.
  • Penis and clitoris have a shaft and glans, become erect, and are sensitive.
