Answer 2

Houses testes and regulates temperature.

Question 3

Where does sperm production occur?

Answer 3

In the seminiferous tubules of the testes.

Question 4

What cells produce testosterone?

Answer 4

Leydig cells.

Question 5

Where does sperm mature and get stored?

Answer 5

Epididymis.

Question 6

What transports sperm during ejaculation?

Vas deferens.

Question 7

What is the function of the seminal vesicles?

Answer 7

Produce fructose-rich fluid to energize sperm.

Question 8

What does the prostate gland secrete?

Answer 8

Alkaline fluid to protect sperm from vaginal acidity.

Question 9

What is the function of the bulbourethral glands?

Answer 9

Secrete mucus to neutralize urine acidity.

Question 10

What is spermatogenesis?

Answer 10

The process of sperm cell development in the testes.

Question 11

What happens in Meiosis I during spermatogenesis?

Answer 11

Primary spermatocytes become secondary spermatocytes (haploid).

Question 12

What is the function of the sperm’s midpiece?

Answer 12

Contains mitochondria to generate energy.

Question 13

What does the acrosome of the sperm contain?

Answer 13

Enzymes to penetrate the egg.

Question 14

What is the function of the ovaries?

Answer 14

Store oocytes and secrete estrogen and progesterone.

Question 15

Where does fertilization typically occur?

Answer 15

In the oviduct (fallopian tube).

Question 16

What is the role of the uterus?

Answer 16

Site of embryo implantation and development.

Question 17

What connects the uterus to the vagina?

Answer 17

Cervix.

Question 18

What is the function of mammary glands?

Answer 18

Produce milk for lactation.

Question 19

When does oogenesis begin?

Answer 19

Before birth.

Question 20

What triggers follicle development?

Answer 20

GnRH stimulates release of FSH and LH.

Question 21

What forms the zona pellucida?

Answer 21

Granulosa cells.

Question 22

What triggers ovulation?

Answer 22

LH surge caused by rising estrogen.

Question 23

What hormone maintains the corpus luteum after fertilization?

Answer 23

hCG (human chorionic gonadotropin).

Question 24

What happens during the follicular phase?

Answer 24

Follicles grow under FSH and LH stimulation.

Question 25

What characterizes the menstrual phase?

Answer 25

Shedding of the endometrium due to low hormone levels.

Question 26

What hormones maintain the endometrium in the secretory phase?

Answer 26

Progesterone and estrogen.

Question 27

What causes menstruation to begin?

Answer 27

Drop in progesterone and estrogen when no fertilization occurs.

Question 28

Why is the scrotum located outside the body?

Answer 28

To keep the testes cooler than body temperature, which is optimal for sperm production.

Question 29

How does the structure of the sperm tail help in reproduction?

Answer 29

The tail (flagellum) allows sperm to swim towards the egg.

Question 30

What would happen if FSH was not released during the ovarian cycle?

Answer 30

Follicle development would not occur, preventing ovulation.

Question 31

How does the corpus luteum help maintain pregnancy in the early stages?

Answer 31

It secretes hormones that maintain the endometrium until the placenta takes over.

Question 32

Why does the endometrium shed during menstruation?

Answer 32

Because hormone levels drop due to corpus luteum degeneration when fertilization does not occur.

Question 33

How is the acrosome of the sperm structurally adapted to its function?

Answer 33

It contains enzymes that help penetrate the protective layers around the egg.

Question 34

What would be the impact of blocked fallopian tubes?

Answer 34

Fertilization would not occur because the sperm cannot reach the egg.

Question 35

How do the structures of the uterus support embryo development?

Answer 35

The thick endometrium provides nutrients, and muscular walls support the growing fetus.
