Reproductive system

Question 1

Is a collection of organs and structures in the body that produce, nurture, and birth children. It contains organs that produce reproductive cells (sperm in males and eggs or ovaries in females), as well as structures for fertilization and the support of developing embryos and fetuses in females.

Answer 1

Reproductive System

Answer 2

Testes

Question 3

Stores and matures sperm.

Answer 3

Epididymis

Question 4

Transports sperm from the epididymis to the urethra.

Answer 4

Vas Deferens

Question 5

Produce seminal fluid to nourish and transport sperm.

Answer 5

Seminal Vesicles

Question 6

Secretes fluid that helps activate sperm.

Answer 6

Prostate Gland

Question 7

Delivers sperm into the female reproductive system.

Answer 7

Penis

Question 8

Conducts semen and urine out of the body

Answer 8

Urethra

Question 9

Produce eggs (ova) and hormones like estrogen and progesterone.

Answer 9

Ovaries

Question 10

Transport eggs from the ovaries to the uterus; site of fertilization.

Answer 10

Fallopian Tubes

Question 11

Supports the implantation and development of a fertilized egg.

Answer 11

Uterus

Question 12

Connects the uterus to the vagina and allows passage of sperm, menstrual blood, or a baby during childbirth.

Answer 12

Cervix

Question 13

Receives sperm, serves as the birth canal, and provides an exit for menstrual flow.

Answer 13

Vagina

Question 14

Produce hormones like estrogen and progesterone, which regulate the menstrual cycle and prepare the body for pregnancy.

Answer 14

Ovaries

Question 15

Secrete testosterone, which regulates sperm production and secondary male characteristics like muscle mass and voice deepening.

Answer 15

Testes

Question 16

Stimulates sperm production, development of male secondary sexual characteristics, and maintenance of libido.

Answer 16

Testosterone

Question 17

Regulates the menstrual cycle, promotes the thickening of the uterine lining, and supports secondary sexual characteristics like breast development.

Answer 17

Estrogen

Question 18

Prepares the uterus for pregnancy, maintains the uterine lining during pregnancy, and inhibits further ovulation.

Answer 18

Progesterone

Question 19

Occurs in the testes. It produces millions of small, motile sperm continuously after puberty.

Answer 19

Spermatogenesis

Question 20

Occurs in the ovaries. It produces a limited number of large, non-motile eggs. Only one mature egg is typically released per menstrual cycle.

Answer 20

Oogenesis

Question 21

Prevent implantation or sperm movement.

Answer 21

IUDs

Question 22

Vasectomy or tubal ligation permanently blocks gamete transport.

Answer 22

Sterilization

Question 23

Stimulates gamete production

Answer 23

FSH FEMALE

Question 24

Triggers ovulation in females and testosterone production in males

Answer 24

LH FEMALE

Question 25

Secrete a pre-ejaculate fluid to neutralize acidity.

Answer 25

Bulbourethral glands

Question 26

A muscular organ that houses and nourishes the developing fetus. During labor, the myometrium contracts to push the baby out.

Answer 26

Uterus

Question 27

The lower portion of the uterus that dilates and softens during labor to allow passage of the baby.

Answer 27

Cervix

Question 28

Inner layer that thickens during the menstrual cycle to support embryo implantation. Sheds during menstruation if pregnancy does not occur.

Answer 28

Endometrium

Question 29

Middle muscular layer responsible for powerful contractions during labor and menstruation.

Answer 29

Myometrium

Question 30

Outer layer that provides structural support and reduces friction with other organs.

Answer 30

Perimetrium

Question 31

Contains connective tissue, blood vessels, lymphatic vessels, and nerves that support the cortex.

Answer 31

Medulla

Question 32

Contains follicles where oocytes (immature eggs) develop. Most ovarian activity occurs here.

Answer 32

Cortex

Question 33

Stimulates the production of milk in the mammary glands

Answer 33

Prolactin

Question 34

Facilitates the ejection of milk (milk letdown reflex) by contracting the smooth muscle around mammary ducts

Answer 34

Oxytocin

Question 35

Stimulates spermatogenesis in the testes by acting on Sertoli cells.

Answer 35

FSH (Follicle-Stimulating Hormone) MALE

Question 36

Stimulates Leydig cells to produce testosterone, which supports sperm production and secondary sexual characteristics.

Answer 36

LH (Luteinizing Hormone) MALE

Question 37

Contracts to pull testes closer to the body in cold temperatures.

Answer 37

Cremaster muscle

Question 38

Contracts to wrinkle the scrotal skin and reduce heat loss.

Answer 38

Dartos muscle

Question 39

Progesterone (from the corpus luteum) and estrogen exert negative feedback to suppress FSH and LH, preventing additional ovulations. If pregnancy does not occur, hormone levels drop, and the cycle restarts.

Answer 39

Luteal Phase

Question 40

What are the effects of testosterone on secondary sexual characteristics and overall male reproductive function?

Answer 40

Deepening of the voice, Supports growth and maintenance of male reproductive organs (e.g., testes and prostate).
