Answer 3

Once a month, an oocyte develops into an ovum (egg) by the process of oogenesis

Question 4

Corpus Luteum

Answer 4

The corpus luteum secretes estradiol and progesterone that helps to maintain pregnancy

Question 5

Oviducts

Answer 5

The egg cell travels from the ovary to the uterus via an oviduct

E.g. Fallopian Tube

Question 6

Uterus

Answer 6

Cilia in the oviduct convey the egg to the uterus, also called the womb

E.g. the womb

Endometrium

Answer 7

The uterus lining, the endometrium, has many blood vessels

• The mammary glands are not part of the reproductive system but are important to mammalian reproduction

Question 13

Testes

Answer 13

The male gonads, or testes, consist of highly coiled tubes surrounded by connective tissue

Question 14

Seminiferous Tubules

Answer 14

Sperm form in these seminiferous tubules

Question 15

Leydig Cells

Answer 15

Leydig cells produce hormones and are scattered between the tubules

Question 16

Scrotum

Answer 16

The testes of many mammals are held outside the abdominal cavity in the scrotum, where the temperature is lower than in the abdominal cavity

Question 17

Epididymis

Answer 17

store the sperms for maturation and transport it to vas deferens

Question 19

Ejaculation

Answer 19

Question 20

Semen

Answer 20

Semen is composed of sperm plus secretions from three sets of accessory glands

Question 21

Seminal Vesicles

Answer 21

The two seminal vesicles contribute about 60% of the total volume of semen

Question 22

Prostate Gland

Answer 22

The prostate gland secretes its products directly into the urethra through several small ducts

Question 23

Penis

Answer 23

• The human penis is composed of three cylinders of spongy erectile tissue
• During sexual arousal, the erectile tissue fills with blood from the arteries, causing an erection
• The head of the penis has a thinner skin covering than the shaft and is more sensitive to stimulation

Question 24

Gametogenesis

Answer 24

the production of gametes

Question 25

Spermatogenesis

Answer 25

the development of sperm

Question 26

Oogenesis

Answer 26

the development of a mature egg

Question 27
