Answer 5

The cervix is the narrow opening to the uterus that allows sperm to enter and menstrual blood to exit.

Question 6

What is the function of the vagina?

Answer 6

The vagina is the muscular canal leading from the cervix to the outside of the body. It’s where sperm is deposited and where a baby passes through during birth.

Question 7

Answer 7

(Diagram would be provided, labels should include: testes, scrotum, sperm duct, prostate gland, urethra, penis)

Question 8

What is the function of the testes?

Answer 8

The testes produce sperm and the male hormone testosterone.

Question 9

What is the function of the scrotum?

Answer 9

The scrotum is a pouch of skin that holds the testes and regulates their temperature.

Question 10

What is the function of the sperm duct?

Answer 10

The sperm duct carries sperm from the testes to the urethra.

Question 11

What is the function of the prostate gland?

Answer 11

The prostate gland produces fluid that mixes with sperm to form semen.

Question 12

What is the function of the urethra?

Answer 12

The urethra carries both urine and semen out of the body (though not at the same time).

Question 13

What is the function of the penis?

Answer 13

The penis delivers sperm into the female reproductive system and allows urine to exit the body.

The menstrual cycle is a monthly series of hormone-driven changes in a female’s body that prepares the uterus for a possible pregnancy.

Question 17

Why is the menstrual cycle important for fertility?

Answer 17

The menstrual cycle involves the release of an egg (ovulation), which is necessary for fertilization.

Question 18

What is the main difference between sperm and egg?

Answer 18

Sperm are small, motile cells that carry male genetic information, while eggs are large, non-motile cells that carry female genetic information.

Question 19

How do sperm and egg meet to form a fertilized egg?

Answer 19

During sexual intercourse, sperm are deposited into the vagina and travel up the fallopian tubes to fertilize the egg.

Question 20

What is the role of the placenta?

Answer 20

The placenta provides oxygen and nutrients to the developing baby and removes waste products.

Question 21

What is the role of the amniotic sac and fluid?

Answer 21

The amniotic sac and fluid cushion and protect the developing baby.

Question 22

What is the role of the umbilical cord?

Answer 28

By comparing and contrasting information from different sources, asking critical questions, and identifying reliable sources.

Question 29

Question 30

Explain how the reproductive systems of humans and other animals are similar and different.

Answer 30

(Answers will vary depending on the specific animals compared, but should focus on similarities like the production of gametes and fertilization, and differences in internal vs. external fertilization, gestation periods, etc.)
