1

Functions of the Prostate Gland

Secretion of substances that become part of the semen

2

Functions of the Urethra

Duct with dual functions; channel for ejaculation of sperm during sexual arousal and for excretion of urine at other times

3

What is the Penis

Male organ of sexual intercourse

4

Functions of the Testis

One of a pair of gonads, packed with small, sperm-producing tubes (seminiferous tubules) and cells that secrete testosterone and other sex hormones

5

What is the Ejaculatory Duct

One of a pair of duct through which sperm travel to the penis

6

What is the Seminal Vesicle

One of a pair of glands that secrete fructose, prostaglandins that become part of semen

7

What is the Bulbourethral Gland

One of a pair of glands that secrete a lubricating mucus

8

What is the Vas Deferens

One of a pair of ducts through which sperm travels to the penis

9

What is the Epididymis

One of a pair of ducts in which sperm complete maturation; the part farthest from a testis stores mature sperm

10

Functions of the Ovary

One of a pair of gonads that produces oocytes and sex hormones. The hormones work on a monthly basis. They stimulate an oocyte to mature and corpus luteum (glandular structure) to form, and prime the uterine lining for potential pregnancy.

11

What is the Clitoris

Small organ responsive to sexual stimulation

12

What is the Labium Minora

One of a pair of innermost thin, skin folds; part of the genitals

13

What is the Labium Majora

One of a pair of outermost, fat-padded skin folds; part of the genitals

14

What is the Vagina

Organ of sexual intercourse; also the birth canal

15

Functions of the Endometrium

Inner lining of the uterus into which a blastocyst implants itself; gets thicker and has increased blood supply during pregnancy; gives rise to maternal portion of placenta, an organ that metabolically supports embryonic and fetal development

16

What is the Myometrium

Thick muscle layers of the uterus; stretch greatly during pregnancy

17

What is the Uterus

Chamber in which embryo develops; its narrow portion, the cervix, secretes mucus that helps sperm travel into the uterus and defends the embryo against many bacteria

18

What is the Oviduct

One of a pair of ciliated channels through which oocytes and propelled from an ovary to the uterus; usual site of fertilization.
