Educational worksheet on human reproductive organs and menstruation, featuring labeled diagrams of male and female reproductive systems and matching functions.

Let's solve each part of this biology task step by step, based on the diagrams and questions provided.

1. Identify the organs in the male and female reproductive systems

We are given two diagrams: one of the male reproductive system (left) and one of the female reproductive system (right). Let’s identify each labeled part.

#### Male Reproductive System (Left Diagram):
- A: Epididymis – a coiled tube where sperm mature and are stored.
- B: Vas deferens – carries sperm from the epididymis to the ejaculatory duct.
- C: Seminal vesicle – produces fluid that mixes with sperm to form semen.
- D: Testis – produces sperm and testosterone.
- E: Scrotum – sac that holds the testes; helps regulate temperature for sperm production.

#### Female Reproductive System (Right Diagram):
- F: Ovary – produces eggs (ova) and hormones like estrogen and progesterone.
- G: Fallopian tube (Oviduct) – where fertilization usually occurs.
- H: Uterus – where a fertilized egg implants and develops into a fetus.
- I: Cervix – the lower part of the uterus that connects to the vagina.
- J: Vagina – the canal leading from the cervix to the outside of the body; receives sperm and is the birth canal.

2. Match the functions of reproductive organs

We need to match the organ names on the left with their correct function on the right.

Given:
- Ovary → Where ova are produced ✔ (already matched)

Now let’s match the rest:

- Uterus → Where a fertilised egg can develop
- Oviduct → Where the ovum can be fertilised
- Cervix → The base of the uterus
- Testis → Where the sperm are produced
- Gland (likely referring to seminal vesicles or prostate) → Produces a fluid for the sperm to swim in
- Penis → Places sperm in the vagina during intercourse
- Sperm duct (also called vas deferens) → Tube carrying sperm out of the penis

✔ Final Matching:

- Ovary → Where ova are produced
- Uterus → Where a fertilised egg can develop
- Oviduct → Where the ovum can be fertilised
- Cervix → The base of the uterus
- Testis → Where the sperm are produced
- Gland → Produces a fluid for the sperm to swim in
- Penis → Places sperm in the vagina during intercourse
- Sperm duct → Tube carrying sperm out of the penis

3a. Puberty Questions

#### i) What happens to a child's body during puberty?

✔ Answer:
During puberty, a child’s body undergoes physical changes as it develops into an adult capable of reproduction. These changes are triggered by hormones and include growth spurts, development of secondary sexual characteristics, and maturation of the reproductive system.

---

#### ii) Give two changes which take place in a girl’s body at puberty.

✔ Answer (any two):
1. Development of breasts
2. Growth of pubic and underarm hair
3. Start of menstruation (menarche)
4. Widening of hips
5. Growth spurt

(Any two of these are acceptable.)

---

#### iii) Give one emotional change which takes place in both boys and girls at puberty.

✔ Answer:
Increased mood swings or emotional sensitivity due to hormonal changes.

(Other possible answers: increased interest in relationships, feelings of self-consciousness, desire for independence.)
