Sponge: Set up Cornell Notes on pg.73 Topic: 22.1 Male and Female
reproductivesystems Essential Question: Describe the majorfunction
of the uterus. 22.1 Male and female reproductive systems Describe
the major function of the uterus. Take out your classwork/homework
from last night Parent permission paper Human Reproduction
Everything comes down to a male gamete (sperm) fertilizing a
femalegamete (egg or ovum) Ensures genetic makeup of the resulting
zygote comes from each parent Ensures genetic variation in the
human species 23 23 46 The Male and Female Reproductive
Systems
The structures of the male and female reproductive systems are
adaptedfor the production and release of the gametes (sperm and
egg) *Structure is ALWAYS related to function 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 reproductivetract Secrete male sex hormones
such as testosterone 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
releasedat 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 Male Reproductive System
Label the male reproductive system- write a short description of
the function of each part p in text Male Reproductive System
Urinary bladder Seminal vesicle Vas deferens (ductus deferentia)
Prostate gland Urethra anus epididymis Erectile tissue of penis
scrotum Testis 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 Testis- (plural
testes- or testicles)
Produces sperm and male hormones Contained within the scrotum Fun
Fact!!! Testes normally drop a month or twobefore birth, but may
take as long as ayear Cryptorchidism is a disorder wherethe testes
fail to descend into thescrotum May need Undescended
testiclerepairis also known as orchiopexy,within the first year of
life If left untreated, the cells that normallyproduce sperm cells
degenerate and themale is infertile, because thetemperature in the
abdominal cavity istoo hot 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 Vas deferens (ductus
deferentia)-
Muscular tubes Transports sperm from epididymis to seminal vesicle
Fun Fact!!! Avasectomyis an operation that makes a manpermanently
unable to get a woman pregnant. It involves cutting the 2 tubes
called vasdeferens so that sperm can no longer get intothe 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. 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 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 Urethra- Tube
connected to bladder for excretion of urine and semen 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 Urinary bladder- collects
urine Anus- opening at which solid waste is excreted P. 72 Crash
Course: Human Reproduction Reproductive Disorder Summary
10-15 bullets Reproductive Disorder Summary The Male and Female
Reproductive Systems
The female reproductive system: Ensures a suitable location for
fertilization Provides an environment for the growth of theembryo
then fetus until birth Female Reproductive System plus
bladder
Label the female reproductive system- write a short description of
the function of each part p in text Female Reproductive System plus
bladder
Uterine tubes a.k.a. Fallopian tubes Ovary Uterus Cervix Urinary
bladder Vagina Urethra Anus Vaginal opening Female Reproductive
System (external/internal detail)
aka fallopian tubes Label the female reproductive system p. 872 in
text (inner lining of uterus) Female Reproductive System
(external/internal detail)
Uterine Tube aka Fallopian Tube aka fallopian tubes Ovaries
Follicles Corpus Luteum Myometrium (Wall of uterus) Uterus
Endometrium (inner lining of uterus) (inner lining of uterus)
Cervix Vagina Ovary- Female reproductive organ in which eggs are
produced Located on each side of the pelvic cavity Fallopian Tubes
(Uterine tube or oviducts)-
Tube through which an ovum (egg) passes from an ovary to the uterus
Uterus- (womb) Hollow, muscular organ Connects cervix and fallopian
tubes Receives the embryo that develops from a fertilized egg Fetus
develops here Endometrium: blood-rich, inner mucous membrane of the
uterus Cervix- Lower part of the uterus Opens to the vagina Opens
for childbirth Vagina- Tube that extends from the uterus to the
outside Open channel for offspring during birth Urethra- tube
connected to bladder for excretion
Urinary bladder- collects urine Anus- opening at which solid waste
is excreted Crash Course: Reproduction System 12m3s
