Describe the male and female reproductive systems, including diagrams, key parts, semen composition, and sperm's journey.

Here are the answers to the questions about the reproductive system:

a. Draw a well labelled diagram of the male and female reproductive systems
The diagram is provided in the question.

b. Identify the following parts:

• I: Seminal vesicle
• II: Vas deferens
• III: Urethra
• IV: Penis
• V: Scrotum
• VI: Testis
• VII: Fallopian tube (or Oviduct)
• VIII: Ovary
• IX: Uterus
• X: Vagina
• XI: Cervix

c. Mention the content of semen
Semen is composed of:

• Sperm (spermatozoa)
• Seminal fluid, which contains:
  • Fructose (for energy)
  • Prostaglandins
  • Clotting factors
  • Enzymes
  • Alkaline fluid (to neutralize vaginal acidity)

d. Outline the path of a sperm from the site of production to the site of fertilisation.

1. Testis (site of production in seminiferous tubules)
2. Epididymis (for maturation and storage)
3. Vas deferens
4. Ejaculatory duct
5. Urethra (exits the male body)
6. Vagina (deposited in female)
7. Cervix
8. Uterus
9. Fallopian tube (site of fertilisation)
