What is the function of the gonads (testes)?

Answer 2

Produce sperm and hormones (like testosterone)

Question 3

Answer 3

Secrete fluids that mix with sperm

Question 4

What is the function of the external genitalia?

Answer 4

Visible outside the body (penis, scrotum)

Question 5

Quick fact

Answer 5

The scrotum keeps testes 2-3 degrees celsius cooler than body temperature, this is ideal for sperm production!

What is the function of the scrotum?

Answer 9

Protects and supports the testes; regulates temperature

Question 10

What are the six parts of the male internal genitalia? (reproductive tract and glands)

Answer 10

Ductus deferens, seminal glands (vesicles), prostate gland, bulbo-urethral glands, epidymis, and testes

Question 11

What is the function of the ductus deferens?

Answer 11

Carries sperm from epidymis to ejaculatory duct

Question 12

What is the function of the seminal glands (vesicles)?

Answer 12

Add fructose-rich fluid (energy for sperm)

Question 13

What is the function of the prostate gland?

Answer 13

Adds enzymes and an antibiotic to semen

Question 14

What is the function of the bulb-urethral glands?

What is erectile tissue?

Answer 20

Specialized tissue that fills with blood during sexual arousal, causing an erection

Question 21

What is the ductus deferens?

Answer 21

A tube that transports sperm from the epidymis to the prostate gland

Question 22

What are the seminal glands?

Answer 22

Glands that secrete fluid to make up most of the semen volume

Question 23

What is the prostate gland?

Answer 23

Produces fluid and enzymes that help nourish sperm

Question 24

What are the bulbs-urethral glands?

Answer 24

Produce lubricating mucus that protects sperm and the urethra

Answer 25

Coiled tube where sperm mature and are stored

Question 26

What are the testes?

Answer 26

Question 27

What are the male gonads called, and what do they produce?

Answer 27

The male gonads are called testes. They produce sperm (gametes) and hormones (like testosterone)

Question 28

Answer 28

Penis, urethra, and scrotum

Question 29

What is the function of the epidymis?

Answer 29

The epidymis is where sperm matures and is stored

Question 30

Which gland secretes fluids that lubricate the tip of the penis?

Answer 30

The bulbo-urethral glands (also called cowper's glands)

Question 31

What is the function of the ductus deferens?

Answer 31

The ductus deferens transports sperm from the epidymis to the prostate gland

Question 32

What are the primary functions of the testes?

Answer 32

Produce sperm and secrete hormones (like testosterone)

Question 33

List all the accessory organs of the male reproductive system

What is the role of the seminal glands?

Answer 37

Secrete fluid that makes up most of the semen volume

Question 38

What is the purpose of the bulbo-urethral glands?

Answer 38

Secrete thick, alkaline mucus that lubricates the tip of the penis and neutralizes acidity

Question 39

What does semen consist of?

Answer 39

Semen = Sperm and secretions from accessory glands

Question 40
