Describe the major function of the uterus.

Parent permission paper

2. Human Reproduction
Everything comes down to a male gamete (sperm) fertilizing a female gamete (egg or ovum)
Ensures ½ genetic makeup of the resulting zygote comes from each parent
Ensures genetic variation in the human species 23 23 46

3. The Male and Female Reproductive Systems
The structures of the male and female reproductive systems are adapted for the production and release of the gametes (sperm and egg)
*Structure is ALWAYS related to function

4. Human Reproduction
The organs of the male reproductive system are specialized to:
Produce/maintain sperm cells
Transport these cells, with supporting fluids, to the female reproductive tract
Secrete male sex hormones such as testosterone

5. Human Reproduction
Semen: The fluid the urethra conveys to the outside during ejaculation
Consists of: Sperm cells and fluids from various glands
2-5 milliliters released at a time
About 120 million sperm per milliliter
Live for many weeks within the ducts of the male reproductive system
Live up to three days after being expelled
Can be stored for YEARS if kept at a temp below -100° C

6. Male Reproductive System
Label the male reproductive system- write a short description of the function of each part
p in text

7. Male Reproductive System
Urinary bladder
Seminal vesicle
Vas deferens
(ductus deferentia)
Prostate gland
Urethra
anus
epididymis
Erectile tissue of penis
scrotum
Testis

8. Scrotum-
Sack of skin that contains the testes, epididymis and part of the vas deferens
Exposure to cold stimulates the muscles to contract, and the testes to move closer to the pelvic cavity
Warmth stimulates the scrotum to hang loosely
Provides an environment about 5° F below body temp

9. Testis- (plural testes- or testicles)
Produces sperm and male hormones
Contained within the scrotum

10. Fun Fact!!!
Testes normally drop a month or two before birth, but may take as long as a year
Cryptorchidism is a disorder where the testes fail to descend into the scrotum
May need Undescended testicle repair is also known as orchiopexy, within the first year of life
If left untreated, the cells that normally produce sperm cells degenerate and the male is infertile, because the temperature in the abdominal cavity is too hot

11. Epididymis-
Tightly coiled tube connected within a testis
Carries sperm from testes to vas deferens
Stores sperm while they finish maturing
Once matured, the sperm cells can move independently

12. Vas deferens (ductus deferentia)-
Muscular tubes
Transports sperm from epididymis to seminal vesicle

13. Fun Fact!!!
A vasectomy is an operation that makes a man permanently unable to get a woman pregnant.
It involves cutting the 2 tubes called vas deferens so that sperm can no longer get into the semen.
F.A.Q:
Q. Will I still be able to ejaculate after vasectomy?
A. Yes, semen is made in the seminal vesicles and the prostate gland. These are not affected by a vasectomy. Sperm make up only 2 to 5 per cent of the ejaculate so you will not be able to notice any difference in the volume of your ejaculate.
Q. Will I still make sperm after my vasectomy?
A. Yes, sperm continue to be made in the testes after a vasectomy. After time, however, production of sperm is often reduced.
Q. After my vasectomy where do the sperm go?
A. The sperm, which are made in the testicles, cannot pass through the vas deferens once they have been cut and tied, so they are reabsorbed by the body.

14. Seminal vesicle-
Saclike gland attached to vas deferens
Secretes an alkaline fluid that makes up 70% of semen
Helps regulate pH
Contains fructose which provides energy to the sperm cells
Chemical which stimulates muscular contractions within the female reproductive organs, aiding in the movement of sperm cells toward the egg

15. Prostate gland-
Chestnut-shaped gland that is inferior to the bladder
Connects the seminal vesicles to the urethra
Secretes an alkaline, milky white fluid that makes up the remaining 30% of semen
Enhances the motility of sperm
Helps neutralize the acidic secretions of the vagina, helping to sustain sperm cells that enter the female reproductive tract

16. Urethra-
Tube connected to bladder for excretion of urine and semen

17. Penis-
Cylindrical organ
Conveys urine and semen through the urethra to the outside
Erectile tissue of penis-
Tissue with vascular spaces to be engorged with blood for erection

18. Urinary bladder- collects urine

19. Anus- opening at which solid waste is excreted

Reproductive Disorder Summary

21. The Male and Female Reproductive Systems
The female reproductive system:
Ensures a suitable location for fertilization
Provides an environment for the growth of the embryo then fetus until birth

22. Female Reproductive System plus bladder
Label the female reproductive system- write a short description of the function of each part
p in text

23. Female Reproductive System plus bladder
Uterine tubes a.k.a. Fallopian tubes
Ovary
Uterus
Cervix
Urinary bladder
Vagina
Urethra
Anus
Vaginal opening

26. Ovary-
Female reproductive organ in which eggs are produced
Located on each side of the pelvic cavity

27. Fallopian Tubes (Uterine tube or oviducts)-
Tube through which an ovum (egg) passes from an ovary to the uterus

28. Uterus- (womb)
Hollow, muscular organ
Connects cervix and fallopian tubes
Receives the embryo that develops from a fertilized egg
Fetus develops here

29. Endometrium: blood-rich, inner mucous membrane of the uterus

30. Cervix-
Lower part of the uterus
Opens to the vagina
Opens for childbirth

31. Vagina-
Tube that extends from the uterus to the outside
Open channel for offspring during birth

32. Urethra- tube connected to bladder for excretion
Urinary bladder- collects urine

33. Anus- opening at which solid waste is excreted
