25
The testes must be at a temperature slightly lower than the _ for proper production of sperm cells.
body temperature (37°C)
26
Where is scrotum situated?
Behind and underneath the penis.
27
A long coiled tube, about 6 meters long, located behind each testis. This duct transports and temporarily stores sperm cells that are produced in the testis. The sperm cells produced in the testis. The sperm cells produced in the testis are immature and not quite ready yet for fertilization. The sperm cells undergo maturation in the _.
Epididymis
28
How long is the epididymis, a long coiled tube?
6 meters
29
Where is the epididymis located?
Behind each testis.
30
Where do the sperm cells undergo maturation?
epididymis
31
Another sperm duct that extends upward from the epididymis. It transports mature sperm cells to the urethra in preparation for ejaculation.
Vas deferens or ductus deferens
32
The discharge of semen through the urethra.
Ejaculation
33
A mixture of sperm cells and various secretions.
Semen
34
Where does the vas deferens or ductus deferens transport mature sperm cells in preparation for ejaculation?
urethra
35
A tube that extends from the urinary bladder to the outside.
Urethra
36
About 20 centimeters in length, conveys urine from the bladder and transports semen to the outside of the body.
male urethra
37
How long is the male urethra in length?
20 centimeters
38
What are the three ducts?
Epididymis, Vas deferens or Ductus deference, Urethra
39
Encloses the urethra. The male organ for sexual intercourse. It is composed of spongy tissue with blood spaces. These blood spaces are relatively empty when the organ is flaccid, but is filled with blood when penis is erect.
Penis
40
This is blocked from the urethra in order to allow only semen to pass through during sexual intercourse.
flow of urine
41
Twisted muscular tubes about 7.5cm long with many sac-like pouches. These are attached to the vas deferens near the base of the bladder. The glandular linings of the _ produce a thick, yellow, an alkaline secretion rich in sugar (fructose) that provides nourishment to the sperm cells.
seminal vesicles
42
How long are the seminal vesicles?
7.5cm
43
The _ of the seminal vesicles produce a thick, yellow, an alkaline secretion rich in sugar (fructose) that provides nourishment to the sperm cells.
glandular linings
44
Located below the urinary bladder, where it surrounds the first part of the urethra. The ducts from the prostate carry its thin, alkaline secretions into the urethra. These fluids also help in nourishing the sperm cells.
Prostate Gland
45
A pair of pea-sized organs located on the sides of the urethra just below the prostate gland.
Bulbourethral Glands
46
Bulbourethral Glands are also referred to as? These glands secrete a clear and slippery fluid that lubricates the urethra and neutralizes acidity due to residual drops of urine in the urethra
Cowper's glands
47
The primary female reproductive organs where the female sex cells or ova are formed. These organs are the counterparts of the male testes.
Ovaries
48
There are _ ovaries, each located on the opposite side of the uterus.
two
49
There are two ovaries, each located on the opposite side of the uterus. Each ovary is small and is somewhat a flattened oval body measuring about?
1.4cm in length, 2cm in width, and 1cm in depth
50
Ovaries serve as a storehouse for? Each month, one of these matures and releases an egg or ovum into the oviduct.
follicles
51
The ovaries also serve in the production of the?
female hormones estrogen and progesterone
52
These are vital for proper reproductive function.
Hormones
53
These extend from the upper sides of the uterus and lead up to the ovaries. These tubes transport the ova to the uterus. It takes about 5 days for an ovum to reach the uterus from the ovary.
Oviduct or Fallopian tubes
54
What do Oviduct or Fallopian tubes transport to the uterus?
ova
55
How many does it take for an ovum to reach the uterus from the ovary?
5 days

57
Uterus is also known as the?
womb
58
What are the measurements of uterus?

corpus or body
61

cervix or neck
62
The lining of the uterus is a specialized epithelial tissue known as _ and is involved in menstruation.
endometrium
63
Implants itself in the endometrium lining and develops in the uterus throughout pregnancy.
fertilized egg
64
Situated between the vagina and uterus. It is the opening through which sperm cells must pass to fertilize an egg. It is also through the cervix where the baby exits the uterus and enters the vagina.
Cervix
65
A tube-like muscular structure measuring about 7.5cm that connects the internal reproductive organs with the external genitalia. It ends at the cervix and is the point and is the point of entry for the penis during sexual activity. It is the final passageway through which a baby exits at birth.
Vagina
66
How long is the vagina?
7.5cm
67
What does the vagina connect?
internal reproductive organs with the external genitalia
68
The male and female gametes differ in?
size, number, mobility
69
Hormones are regulated by _ that secretes more GnRH.
Hypothalamus
70
Since Hypothalamus secretes more GnRH, it causes?
Anterior Pituitary Activation
71
Anterior Pituitary Activation releases?
luteinizing hormone (LH) and follicle-stimulating hormone (FSH)
72
Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) stimulate and control?
Spermatogenesis and Oogenesis
73
The chemical substances secreted by the endocrine glands that have specific regulatory effects on cells in the different parts of the body.
Hormones
74
These contain hormone-containing vesicles that release the hormones directly into the bloodstream going into the target cells.
endocrine glands
75
Some hormones, such as _ affect many tissues. Others affect only specific tissues.
growth hormones, insulin, thyroid hormones
76
This hormone acts only on the thyroid glands.

78
Most of the hormones enter this to reach specific target cells.
bloodstream
79
These are those acted upon specific hormones.
target cells
80
They have receptors on the surface of their plasma membrane or within their cytoplasm that recognize only specific hormones.
Cells
81
A protein molecule to which the hormone attaches.
receptor molecule
82
A binding site that causes the target cell to perform a specific action.
hormone-receptor complex
83
_ of hormones in the blood can cause specific regulatory effects on target cells or organs.
