Lesson Review: Circle the correct term

1. The changes that occur monthly in the female reproductive system are called the (menstrual / ovulation) cycle.
✔ Answer: *menstrual*
👉 The menstrual cycle refers to the entire monthly process involving ovulation, hormone changes, and menstruation.

2. The release of a mature egg from the ovary is called (menstruation / ovulation).
✔ Answer: *ovulation*
👉 Ovulation is when the ovary releases a mature egg.

3. The process by which blood and tissue from the lining of the uterus break apart and leave the body is called (menstruation / ovulation).
✔ Answer: *menstruation*
👉 Menstruation is the shedding of the uterine lining.

4. When a female is born, her body contains (all / none) of the eggs she will have in her lifetime.
✔ Answer: *all*
👉 Females are born with all the eggs they will ever have (about 1–2 million), and these decrease over time.

5. The menstrual cycle occurs about every (28 / 48) days.
✔ Answer: *28*
👉 The average menstrual cycle is 28 days, though it can vary.

6. When a mature egg leaves the ovary, it enters the (cervix / oviduct).
✔ Answer: *oviduct*
👉 The oviduct (also called the fallopian tube) is where the egg travels after ovulation.

7. For most females, the menstrual cycle continues until about age (30 / 50).
✔ Answer: *50*
👉 Menopause typically occurs around age 50, ending the menstrual cycle.

8. The menstrual cycle is triggered by the release of (eggs / hormones) in the female reproductive system.
✔ Answer: *hormones*
👉 Hormones like FSH, LH, estrogen, and progesterone regulate the menstrual cycle.

Skill Challenge: Sequencing the Menstrual Cycle

We are asked to number the stages 1 through 5, starting with menstruation.

Let’s analyze each image:

#### A. Ovulation occurs
→ This is when the egg is released from the ovary. This happens mid-cycle, around day 14.

#### B. Menstrual blood discharges
→ This is menstruation, the first stage of the cycle. The uterine lining sheds.

#### C. Egg enters uterus
→ After traveling through the oviduct, the egg reaches the uterus. This happens after ovulation.

#### D. Egg develops
→ This is the follicular phase, when the egg matures in the ovary before ovulation.

#### E. Egg moves through oviduct
→ After ovulation, the egg travels from the ovary into the oviduct.

---

Now let’s sequence them correctly, starting with menstruation:

1. B. Menstrual blood discharges → Start of cycle
2. D. Egg develops → Follicles grow in the ovary
3. A. Ovulation occurs → Egg is released
4. E. Egg moves through oviduct → Egg travels toward uterus
5. C. Egg enters uterus → Egg reaches the uterus

✔ Final Answers:

#### Lesson Review:
1. menstrual
2. ovulation
3. menstruation
4. all
5. 28
6. oviduct
7. 50
8. hormones

#### Skill Challenge:
- A. 3
- B. 1
- C. 5
- D. 2
- E. 4

📌 Summary of the Menstrual Cycle Stages:

1. Menstruation – Shedding of uterine lining
2. Follicular phase – Egg develops in ovary
3. Ovulation – Egg is released
4. Transport – Egg moves through oviduct
5. Implantation preparation – Egg enters uterus; if fertilized, implantation may occur

This cycle repeats monthly unless pregnancy occurs.
