Male Reproductive System & Function

Question 1

Spongy tissue containing small blood vessels and nerves.

Question 2

Foreskin

Answer 2

EXTERNAL
the skin around the head of the penis

Question 3

A sac of loose skin that holds the testicles.

The scrotum contains muscles that can move the testicles closer to or farther away from the body depending on the temperature.

Question 4

Testicles

Answer 4

INTERNAL
Two oval glands that continuously produce testosterone and sperm.

Question 5

Epididymis

Answer 5

INTERNAL
A sac of tubes on the top of each testicle where sperm is stored and matures before being transported to the Vas Deferens.

Question 6

Vas Deferens

Answer 6

INTERNAL
The small tubes that transport mature sperm from the epididymis up to the seminal vesicles.

Question 7

Seminal Vesicles

Answer 7

INTERNAL
Two small glands that produce fluids that feed and protect the sperm

Question 8

Prostate Gland

Answer 8

INTERNAL
A single walnut-sized gland located just below the bladder, responsible for secreting fluid that nourishes and protects the sperm.

Question 9

Urethra

Answer 9

INTERNAL
A tube in the penis that allows urine out of the bladder and allows semen out of the body during ejaculation.

Urine and semen cannot be in the urethra at the same time.

During an erection, a small valve seals the bladder so that urine cannot get into the urethra.

Question 10

Internal Male Anatomy

Answer 10

Testicles
Epididymis
Vas deferens
Seminal vesicles
Prostate gland
Urethra

Question 11

External Male Anatomy

Answer 11

Scrotum & Penis

Question 12

Sperm

Answer 12

Sperm production begins in puberty.

The male reproductive cells are made daily in the testicles.

Sperm mature in the epididymis, and travel up the Vas Deferens during sexual arousal.

Question 13

Semen

Answer 13

The combination of sperm and fluid from the seminal vesicles and prostate gland that is ejaculated from the urethra.

Question 14

Erection

Answer 14

During sexual arousal, the brain sends a message to the body to increase blood flow to the spongy tissue in the penis.

This causes the penis to harden which allows the penis to be inserted into the vagina.

The release of semen and sperm from the penis, usually as a result of an orgasm.

200-500 million sperm are released during ejaculation
