Worksheet on human reproductive organs and menstruation, including diagrams, labeling exercises, function matching, and puberty-related questions.

Problem Analysis:

The task involves identifying parts of the male and female reproductive systems, matching their functions, and answering questions about puberty. Let's solve each part step by step.

Part 1: Identifying Organs in the Diagrams

#### Male Reproductive System (Left Diagram)
- A: Vas deferens
- B: Seminal vesicle
- C: Prostate gland
- D: Testis
- E: Penis

#### Female Reproductive System (Right Diagram)
- F: Ovary
- G: Fallopian tube (oviduct)
- H: Uterus
- I: Cervix
- J: Vagina

Part 2: Matching Functions of Reproductive Organs

We need to match each organ with its function. Here are the correct matches:

1. Ovary → Where ova are produced
2. Uterus → Where a fertilized egg can develop
3. Oviduct → Tube carrying sperm out of the penis (Note: This is incorrect; the oviduct is where the ovum can be fertilized. The sperm duct carries sperm out of the penis.)
4. Cervix → The base of the uterus
5. Testis → Where the sperm are produced
6. Gland → Produces a fluid for the sperm to swim in
7. Penis → Places sperm in the vagina during intercourse
8. Sperm duct → Tube carrying sperm out of the penis

Corrected matches:
- Ovary → Where ova are produced
- Uterus → Where a fertilized egg can develop
- Oviduct → Where the ovum can be fertilized
- 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

Part 3: Questions About Puberty

#### 3a(i): What happens to a child's body during puberty?
During puberty, the body undergoes significant physical, hormonal, and emotional changes. These changes are driven by the release of hormones such as estrogen (in girls) and testosterone (in boys). The body begins to mature sexually, preparing for reproduction.

#### 3a(ii): Give two changes which take place in a girl’s body at puberty.
1. Menarche: The onset of menstruation, which marks the beginning of a girl's menstrual cycle.
2. Breast Development: The breasts grow and develop, becoming more prominent.

#### 3a(iii): Give one emotional change which takes place in both boys and girls at puberty.
One common emotional change during puberty is an increase in mood swings and emotional sensitivity. Hormonal fluctuations can lead to heightened emotions, making individuals more prone to feelings of anxiety, irritability, or sadness.
