Biology 8 Lesson 61: Female genitalia
1. Summary of theory
1.1. Parts of female genitalia
The organ that produces eggs is the ovary.
The egg is collected into the fallopian tube through the fallopian tube.
Next to the fallopian tube is the uterus located behind the bladder, where the fertilized egg is placed to implant and develop into a fetus. The uterus (or uterus) connects to the vagina through a hole in the cervix.
– Outside, from top to bottom, there is a clitoris corresponding to a male penis
– Below is a tube that carries urine to the bladder, then to the vagina, leading to the uterus.
– Belonging to the female reproductive organs, there are two vestibular glands located on both sides of the vagina, with holes pouring into the baby’s lips near the mouth, secreting oily secretions like onion glands in men.
1.2. Ovaries and eggs
Eggs are produced from the ovaries starting at puberty.
Eggs are larger than sperm, contain many nutrients, and cannot move
– Eggs have only one type (X).
– Eggs can live in the uterus for 2-3 days and can only be fertilized within 1 day if they meet sperm.
2. Illustrated exercise
Lesson 1: When does the female body start producing eggs?
A. New born
- Choose the answer: NO
- Explanation: Eggs are born from the ovaries starting at puberty
Lesson 2: Characteristics NOT of eggs?
A. Large size
B. Contains many nutrients
C. Can’t move
- Choose the answer: EASY
- Explanation: Eggs are larger than sperm, contain many nutrients, and are immobile
Lesson 3: How many eggs does a baby girl have at birth?
- In the fifth month of pregnancy, the fetal ovaries contain about 7 million eggs. But at birth, a girl’s ovaries contain only about 2 million eggs, by puberty there are about 400,000 eggs left.
3.1. Essay exercises

D. All of the above answers
Question 3: Which part of the female reproductive system is responsible for producing eggs?
B. Fallopian tubes
Verse 4: Which organ is responsible for receiving and collecting fertilized eggs?
B. Fallopian tubes
Question 5: What is the function of the vestibular gland in the female reproductive system?
A. Neutralizes acid in the urinary tract
B. Make semen
C. Oily secretions
After completing this lesson, you should know the following requirements:
- Name and identify on the picture the parts of the female reproductive organs. State the basic function of each part, state the characteristics of the egg
- Communication skills: confidently tell the group and class the names of the parts of the female reproductive organs and their functions.
- Ability to collect and process information when reading textbooks, observing pictures to learn the structural and functional characteristics of parts of the female reproductive organs.
