Answer 1

All of your answers were correct except Question 10. Here are the correct answers with short explanations:

1) How long does an egg live after its release from the ovary?
- Correct: 1 day
- Explanation: Once ovulated, the egg is viable for about 12–24 hours.

2) How many days can sperm live inside a woman’s body?
- Correct: 3 to 5 days
- Explanation: Under ideal cervical and uterine conditions sperm can survive up to about 5 days.

3) How many sperm does a man release when he ejaculates inside a woman’s vagina?
- Correct: about 300 to 400 million
- Explanation: A typical ejaculation contains hundreds of millions of sperm (counts vary).

4) When does fertilization occur?
- Correct: the union of the egg and sperm
- Explanation: Fertilization is the sperm entering the egg (usually in the fallopian tube).

5) How many eggs does a woman typically release every month during ovulation?
- Correct: 1
- Explanation: Normally one mature follicle releases one egg each cycle.

6) How many weeks is a full-term pregnancy?
- Correct: 40
- Explanation: Full term is about 40 weeks from the last menstrual period.

7) When in a pregnancy are birth defects most likely to happen?
- Correct: the first trimester
- Explanation: Organogenesis occurs in the first trimester, so exposures then carry highest risk.

8) What happens during the afterbirth?
- Correct: The mother delivers the placenta and umbilical cord.
- Explanation: The third stage of labor is delivery of the placenta and membranes.

9) Which situation is not a reason why a woman might need a Cesarean section (C-section) delivery?
- Correct: The baby has a negative blood type.
- Explanation: A baby’s negative blood type is not an indication for C-section. Indications include breech presentation, cord prolapse or cord around the neck causing compromised oxygen, placenta previa, fetal distress, labor that fails to progress, etc.

10) Which stage of childbirth is known as delivery?
- Correct answer: the second stage
- Explanation:
- First stage: labor — onset of true contractions to full cervical dilation (10 cm).
- Second stage: delivery — from full dilation to birth of the baby (this is the “delivery” stage).
- Third stage: afterbirth — delivery of the placenta and membranes.
