Step-by-step solution for: Reproductive system Worksheet - WordMint
Let's solve this matching exercise step by step. We are given 18 statements (numbered 1–18) on the left and a list of terms (A–R) on the right. Our goal is to match each statement with the correct term from the list.
---
1. These are the primary reproductive organs and include the testes in males and ovaries in females.
→ The gonads (testes and ovaries) are the primary reproductive organs.
✔ Answer: O. Gonads
---
2. These are the sex cells and include the spermatozoon in males and oocytes in females
→ Sex cells are called gametes (sperm and eggs).
✔ Answer: R. Gametes
---
3. These structures include penis and prostate.
→ These are male accessory organs involved in reproduction.
✔ Answer: C. Male reproductive organs
---
4. These structures include uterus and breasts
→ These are female accessory organs.
✔ Answer: H. Female accessory organs
---
5. Tightly coiled comma-shaped tube that lies behind and on top of each testicle.
→ This describes the epididymis, where sperm mature.
✔ Answer: I. Epididymis
---
6. Passageway used to transport mature sperm cells from the epididymis out of the body during ejaculation.
→ The vas deferens carries sperm from the epididymis to the ejaculatory duct.
✔ Answer: D. Vas deferens
---
7. Tube that connects the epididymis to the ejaculatory duct.
→ Again, this is the vas deferens.
✔ Answer: D. Vas deferens
> Note: Both #6 and #7 refer to the same structure — vas deferens.
---
8. Cells within the testes that produce testosterone.
→ Interstitial cells of Leydig (Leydig cells) produce testosterone.
✔ Answer: J. Interstitial cells of leydig
---
9. Lower narrow region of the uterus that opens into the vagina.
→ This is the cervix.
✔ Answer: P. Cervix
---
10. Tubes that serve as passageways for ova as they travel from ovaries toward the uterus.
→ These are the fallopian tubes (also called uterine tubes).
✔ Answer: A. Fallopian tube
---
11. Series of hormonal events that begin during puberty, occurs approximately every 28 days and ends during menopause.
→ This describes the menstrual cycle.
✔ Answer: G. Menstrual cycle
---
12. Periodic discharge of the endometrial lining from the nonpregnant uterus.
→ This is menstruation.
✔ Answer: Q. Menstruation
---
13. Paired glands located lateral to the uterus that possess both endocrine and exocrine function.
→ The ovaries produce hormones (endocrine) and release ova (exocrine-like).
✔ Answer: E. Ovaries
---
14. Flattened organ in the pregnant uterus that nourishes the developing fetus.
→ This is the placenta.
✔ Answer: F. Placenta
---
15. Canal that extends from the cervix to outside of the body.
→ This is the vagina.
✔ Answer: N. Vagina
---
16. The secretion and ejection of milk by the mammary glands.
→ This process is called lactation.
✔ Answer: M. Lactation
---
17. The penetration of the ovum by the sperm.
→ This is fertilization.
✔ Answer: L. Fertilization
---
18. Enables the uterus to maintain pregnancy.
→ The hormone hCG (human chorionic gonadotropin) helps maintain the corpus luteum and supports pregnancy.
✔ Answer: K. hCG
---

| 15 | Canal from cervix to outside body | N. Vagina |
| 16 | Milk secretion and ejection | M. Lactation |
| 17 | Sperm penetrates ovum | L. Fertilization |
| 18 | Maintains pregnancy | K. hCG |
---
- Gonads (O) = primary reproductive organs
- Gametes (R) = sex cells
- Male/Female accessory organs (C/H) = secondary structures
- Epididymis (I), Vas deferens (D) = male duct system
- Leydig cells (J) = testosterone producers
- Cervix (P), Vagina (N), Uterus, Ovaries (E) = female reproductive anatomy
- Fallopian tubes (A) = site of fertilization
- Menstrual cycle (G), Menstruation (Q) = monthly changes
- Placenta (F) = fetal nourishment
- Lactation (M), Fertilization (L), hCG (K) = key processes/hormones
This completes the matching exercise correctly! Let me know if you'd like a printable version or explanation of any term.
