Worked Solution & Example Answer:A = Vagina B = Womb or Uterus C = Ovary D = Fallopian Tube or Oviduct (a) Produce eggs or hormones (oestrogen, progesterone) (b) Blockage of Fallopian tubes or hormonal or failure to ovulate or excessive exercise - Leaving Cert Biology - Question 3 - 2019
Step 1
(a)
Answer
- Label each part:
- A = Vagina
- B = Womb or Uterus
- C = Ovary
- D = Fallopian Tube or Oviduct
- Comprehension of functions:
- The vagina is involved in sexual intercourse and serves as the birth canal during delivery.
- The womb (or uterus) is where embryonic development occurs.
- Ovaries produce eggs (ova) and hormones such as oestrogen and progesterone.
- Fallopian tubes facilitate the passage of eggs from the ovaries to the uterus.
Step 2
(b)
Answer
-
Function of hormones:
- Ovaries produce hormones (oestrogen, progesterone) which are critical for regulating the menstrual cycle and pregnancy.
- They also produce eggs necessary for reproduction.
-
Effects of hormonal imbalance or blockage:
- Blockage of Fallopian tubes can prevent egg fertilization and thus, conception.
- Failure to ovulate can occur due to hormonal issues or excessive exercise, impacting fertility.
Step 3
(c)
Answer
-
Reproductive structures:
- The womb (uterus) and its lining (endometrium) play crucial roles in the reproductive process.
- If an egg is fertilized, it implants into the lining of the uterus.
-
Function of the lining:
- The endometrium thickens in preparation for a potential pregnancy and is shed during menstruation if fertilization does not occur.
