    • What does the red line in the menstrual cycle graph represent?
      The thickness of the uterus lining
    • What happens during stage one of the menstrual cycle?
      Menstruation occurs with bleeding
    • How long does menstruation typically last?
      About four days
    • What occurs during stage two of the menstrual cycle?
      The uterus lining builds up again
    • How long does stage two last?
      Around ten days
    • What is the purpose of the thick spongy layer formed in stage two?
      To prepare for a fertilized egg
    • What happens during stage three of the menstrual cycle?
      Ovulation occurs with egg release
    • How long does ovulation last?
      One day
    • What occurs during stage four of the menstrual cycle?
      The uterus lining is maintained
    • How long does stage four last?
      From day 14 to day 28
    • What happens if no fertilized egg reaches the uterus?
      The uterus lining breaks down
    • What happens if a fertilized egg implants in the uterus?
      The menstrual cycle stops
    • What hormones are involved in the menstrual cycle?
      • Estrogen
      • Progesterone
      • Luteinizing hormone (LH)
      • Follicle stimulating hormone (FSH)
    • What hormone stimulates the uterus lining to grow?
      Estrogen
    • When does estrogen level increase during the cycle?
      During stage two
    • What role does progesterone play in the menstrual cycle?
      Maintains the lining of the uterus
    • What happens if progesterone levels drop?
      The uterus lining breaks down
    • Where are LH and FSH produced?
      In the pituitary gland
    • What is the role of FSH in the menstrual cycle?
      Stimulates egg maturation in ovaries
    • What does LH stimulate on day 14?
      The release of the egg
    • How do the hormones interact during the menstrual cycle?
      • FSH stimulates estrogen production
      • Estrogen inhibits FSH (negative feedback)
      • High estrogen levels stimulate LH release
      • Progesterone inhibits both LH and FSH
    • What is an example of negative feedback in the menstrual cycle?
      Estrogen inhibits FSH production
    • What happens when estrogen levels are high?
      They stimulate the release of LH
    • What does progesterone inhibit?
      Both LH and FSH
