25
What are the 3 transport tubes in the male reproductive system?
Vas deferens, urethra, ejaculatory duct
26
What is another name for the vas deferens?
Ductus deferens
27
This organ conveys mature sperm from the epididymis to the ejaculatory ducts near the urethra.
Vas deferens
28
It carries sperm out of the body.
Urethra
29
This organ extends to the prostate gland and joins with the urethra in the prostate gland.
Ejaculatory duct
30
What are the 3 accessory glands of the male reproductive system?
Seminal vesicle, prostate gland, Bulbourethral/Cowper's gland
31
This gland secretes an alkaline fluid that contains sugar, which energizes the sperm.
Seminal vesicle
32
This gland releases a milky fluid that liquefies the semen, making the sperm move faster.
Prostate gland
33
True or False: The fluid secreted by the prostate gland makes up 25% of the semen.
TRUE
34
Which gland secretes an alkaline substance in the urethra that neutralizes acid from the urine?
Bulbourethral/Cowper's gland
35
What are the three main parts of the sperm cell?
Head, midpiece, tail
36
In what part of the sperm can its mitochondria be found?
Midpiece
37
Where is the sperm's genetic material located?
Head
38
It is used by the sperm for movement.
Tail
39
What s the purpose of the acrosome?
It is an acidic vacuole that contains a number of hydrolytic enzymes which can help penetrate the egg.
40
Where is the acrosome located?
Head
41
Why does the sperm have a plasma membrane on its tail?
To protect sperm against extracellular injuries & to respond to physiological challenges.
42
True or False: The optimum temperature for sperm cell production is higher than the normal body temperature.
FALSE. Optimum temperature is 34 degrees, lower than the normal body temperature of 37 degrees.
43
What is the optimum temperature for the sperm cell to survive?
20 degrees Celsius, 15-30 minutes after ejaculation
44
True or False: If the sperm is ejaculated, it can live for up to 5 days inside a female's vagina.
TRUE
45
Up to how many days can a sperm live in a male's body if it is not ejaculated?
74 days
46
How long can a sperm cell live if it is released into the open?
20-30 minutes?
47
What are the internal parts of the female reproductive system?
Ovaries, fallopian tubes, uterus, vagina, cervix
48
These paired organs produce the egg and secrete hormones.
Ovaries
49
These organs catch the egg from the ovary and transport it to the uterus.
Fallopian tubes

59
What is the active hormone in mammary glands?
Prolactin
60
What is the role of the prolactin hormone?
For inducing milk production
