Q

a bag of skin that contains the testes

A

scrotum

21
Q

a reproductive structure that is located under the penis

A

Scrotum

22
Q

The scrotum is about 2–3°C lower than the normal body temperature, and this is the temperature that is favorable for sperm cell production and development.

A
23
Q

Within the scrotum are muscles known as the

A

dartos and cremaster muscles

24
Q

When environmental temperature is too low, the _ contracts, which decreases the surface area of the scrotum in contact with the outside environment. This prevents further heat loss.

A

dartos

25
Q

brings the testes closer to the body to conserve heat.

A

cremaster

26
Q

is the external part of the male reproductive system. It is a tube-shaped organ that contains the urethra, which allows it to pass the urine and semen out of the body

A

penis

27
Q

also known as the head of the penis, is a sensitive structure at the end of the organ. It contains the opening for the urethra

A

glans penis

28
Q

The glans penis is covered by skin known as the _, which protects the glans.

A

prepuce

29
Q

Within the penis is a structure known as the _ _. This structure is known as the erectile tissue in men, which leads to the penis becoming erect when the _ _ is filled with blood. This is in preparation for sexual intercourse.

A

corpora cavernosa

30
Q

are composed of the vas deferens and seminal vesicles.

A

Sperm ducts

31
Q

a tube through which sperm cells pass before entering the urethra

A

vas deferens

32
Q

secrete fluid that makes the sperm cells more mobile, increasing the chances of fertilization

A

Seminal vesicles

33
Q

a structure associated with the vas deferens. Its primary function is to hold and support structures like blood vessels and the vas deferens itself

A

spermatic cord

34
Q

These glands secrete substances that aid in the nourishment of sperm and contribute to higher chances of fertilization.

A

accessory glands

35
Q

accessory glands

A

seminal vesicles
bulboyrethral gland
prostate gland

36
Q

has secretions that serve to neutralize the vagina’s acidity.

A

bulbourethral gland

37
Q

secretes the prostate fluid

A

prostate gland

38
Q

neutralizes the acidic conditions of the vagina

A

prostate fluid

39
Q

mixture of sperm and prostate fluid is called

A

semen

40
Q

The muscles of the prostate gland help propel semen through the urethra and into the female reproductive organ during ejaculation

A
41
Q

a tube beside the testes

where mature sperms are stored

A

epididymis

42
Q

The sperm cells are stored until they are released from the body through a process known as

A

ejaculation

43
Q

forcefully expels sperm and semen from the male body into the female’s vagina during sexual intercourse

A

Ejaculation

44
Q

proteins in the epididymis serve to support the reproductive tract of males, protect against bacterial infections, and regulate recovery after a bacterial infection

A

defensins

45
Q

During ejaculation, sperm moves from the epididymis, into a tube called the _ _, into another tube known as the urethra, and out of the bod

A

vas deferens

46
Q

a method of birth control that deals with cutting or blocking the tube of the vas deferens. This prevents sperm cells from being transported out of the body and will lead to future sexual intercourse by the affected male to carry no risk of fertilization.

A

vasectomy

47
Q

is connected to both the urinary bladder and sperm duct. This is the reason why the urethra serves as an exit point for both urinary and reproductive products.

A

Urethra

48
Q

The production, development, and maturation of sperm cells happens within the male reproductive system.
The type of gametogenesis that occurs in male organisms is known as spermatogenesis.
The male reproductive system is composed of the testes, scrotum, urethra, penis, sperm ducts. and accessory glands
The gonads of the male reproductive system are the testes. Each male reproductive system has two testes.
