1. The Human Reproductive Systems

2. Female and male reproductive organs fully develop during puberty.

3. The Female Reproductive System

4. There are 2 main functions of the female reproductive system.
1) produce ova, or egg cells (gametes)
2) provide a place where a zygote develops
uterus
cervix
rectum
vagina
urethra
urinary bladder
ovary
fallopian
tube
Side View

5. Main organs of the Female Reproductive System
Organ Functions:
Ovary: Releases ovum (egg) and female hormones
Fallopian tubes (Oviducts): Carries ovum to uterus and site of fertilization
Uterus: where fertilize egg will implant and offspring will develop
Cervix: area between uterus and vagina
Vagina: where unfertilized eggs pass through menstruation OR birth canal for baby

6. Main Female Hormone: Estrogen
Released by the ovaries
Estrogen has three main functions.
develop female sexual characteristics
develop eggs
prepare uterus for
pregnancy

7. Tues. 4/9/19 Kahoot Female

8. The Male Reproductive System

9. Main organs of the Male Reproductive System:
There are 2 main functions of the male reproductive system.
1) produce sperm cells
2) deliver sperm to the female reproductive system
urinary bladder
vas deferens
prostate gland
penis
urethra
testis
scrotum
epididymis
rectum
seminal vesicle
Side View

10. Organs: Organ Functions:
Testis: Produce sperm and male hormones; 2= testes
Epididymis: sit above (epi= top) of each testis; where sperm go to mature
Vas deferens: tube that sperm travels through, from epididymis to penis
Seminal vesicle and prostate gland: provide nutrients/fluid for sperm
Penis: male organ to deliver sperm into vagina of female.
Urethra: tube in penis where sperm AND urine will leave male body. (*separate in females!)
Organs:

11. Sperm pathway
Testes -> epididymis -> Vas deferens -> urethra

12. EOC Review
Sperm are created through meiosis in an area of the testes called the seminiferous tubules. Through which structure do the sperm travel to exit the testes? 
A. vas deferens
B. seminiferous tubules
C. scrotum
D. epididymis

13. Main Male Hormone: Testosterone
Testosterone has 2 main functions.
1) developing male sexual characteristics
2) producing sperm
*label male reproductive organs practice
(Quiz yourself!)

14. Other important hormones:
Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are found in BOTH males and females.
Females: FSH, LH and estrogen regulate egg production.
Males: FSH, LH, and testosterone stimulate sperm production.

15. Human Fetal Development

16. Ovulation – Release of the egg from ovary (know the pathway!)
2) Travels through
Fallopian
tube
egg cell
1) egg released
from ovary
**Implantation or passes
out of body through
cervix, then vagina
ovary
3) Enters uterus
5 to 7 days to uterus
**Site of fertilization!

17. Fertilization occurs when a sperm cell joins an egg cell.
Sperm penetrates an egg.
nucleus of sperm joins with egg
zygote formed

18. Fertilization Video 6 minutes: https://www. youtube. com/watch

19. Weds. 4/10/19 Kahoot Male

20. EOC Review Which of the following describes fertilization?
cell differentiation to form a blastula
formation of eggs in the ovaries
a sperm joining an egg to form a zygote
sperm and egg production

21. Multiple zygotes

22. Fetal Development Development progresses in stages from zygote to fetus.

23. Once the zygote implants in the uterus, it is called an embryo.
After fertilization:
A zygote begins MITOSIS after fertilization and is called a blastocyst (ball of cells)
Once the zygote implants in the uterus, it is called an embryo.
Blastocyst
(Fertilized Egg)
uterine wall
Implantation

24. Once implanted, membranes develop to protect and nourish the embryo.
amniotic sac cushions embryo with water.
placenta connects mother and embryo. *connected to uterus wall
umbilical cord connects embryo to placenta.
placenta
umbilical cord
uterus
amniotic sac

25. A fully formed fetus in about 38-40 weeks.
Human pregnancies are divided into trimesters.
1st trimester: body plan and early development of major organs; (BRAIN and HEART)

26. 2nd trimester: fetus more active; more development of skeletal and muscular system

27. 3rd trimester: all organs fully formed; LAST TO FULLY DEVELOP are the LUNGS!
After about 38 weeks, fetus is ready to be born.

29. EOC Review
A fertilized egg undergoes several stages before it is successfully implanted. The diagram below shows these stages as the fertilized egg travels through the female reproductive system. 
                                                                                        In which of the following structures of the female human reproductive system is the blastocyst implanted during normal human development? 
A. ovary
B. uterus
C. vagina
D. amniotic sac

30. EOC Review
The drinking of alcoholic beverages by a pregnant woman is harmful to the development of her fetus. This is most damaging EARLY in a pregnancy because during this time
the lungs of the fetus become functional.
alcohol can easily enter the mouth of the fetus.
the fetus cannot excrete wastes.
many of the essential organs of the fetus are forming.
