Produces female gametes (called) egg cells : A fertilised egg cell develops (into) a fetus.
Formed by external sex organs (or genitals) and internal sex organs .External female sex organs (include) various parts : this parts together are called vulva :
– Labia majora and labia minora = protect the rest of the vulva .
– Vagina orifice = leads into the vagina .
– Clítoris = sensitive sex organ .
The internal female sex organs are (located) inside the PELVIS.
The male reproductive system produces male gametes,called sperm cells.it also it also tansports the sperm cells out of a man body andinto a woman reproductive system
·the penis:which deposits sperm cell im the vagina.
·the testicles:produces millions of sperm cells.
·the vas deferens: caries sperm cell to the urethra.
·seminal vesicles and the prostate wich produce liquids to make semen tahat contains sperm cells alive outside the mans body
·the urethra which carries the semen and the sperm cells through the penis
the vas deferens is a tube that carries sperm cells from the testicle to the seminal vesicles
the penis is an elastic organ whith a cylindrical shape
the urethra is a tube thatgoes from the bladder yhrough the prostate
the seminal vesicles are two small glands and produce a liquid that becomes part of the semen
the prostate is a lrge gland that produces a milky white liquid this also become part of the semen
the testicles are two oval organs that produce sperm cells
HOW THE MALE REPRODUCTIVE SYSTEM WORKS
When a sperm cell fertilises an egg cell, the two cells made a baby
A girl (Alessandra Ambrosio)
+
A boy (Theo james)
=
A baby( a little baby of we heart it)
All this process is made in 9 months
The sperm cell move their tails and they do like a “race” to the egg cell. After fertilization , the zygote travels down the fallopian tube to the uterus . As it travels, the zygote travels down the fallobian tube to tue uterus. Zygote divides many times to form a group of cells called an embarayo.
An embarayo is when a baby its in the gut
Pregnancy is the time between the fertilisation of an egg cell and the birth of a baby.
For human mothers, pregnancy lasts for about nine months. During this, time special organs form inside the uterus: the placenta and the amniotic sac.
Birth is when a baby leaves the uterus though the vagina.
First the wallsof the uterus starr to contract in a rhymic way the cervix dilates. Baby come out of the uterus. Then the amniotic sac uterus.
Next, the baby is expelled through vagina. It usually comes out head-first. After that, the baby started to breath.
Finally, the uterus contracts again and the afterbirth is expelled. The afterbirth includes the placeta and the umbilicar cord
THE MENSTRUAL CYCLE
Activities together are (called ) menstrual cycle.
Womans menstrual cycle include ovarian cycle and uterine cycle.
O.C : egg cell starts inside of the ovaries .14 day of ovarian cycle the egg cell leave ovarie .(This process is called OVULATIN)
U.C : Wall of uterus bacame thicker with extra tissue and blood come away from walls , leave body through vagina .(This process is called OVULATION)
Sexual reproduction is how humans begings have childrens. This process involes the combination of female and male reproductive cells.
SEX CHARACTERISTIC
These are physical difference between male and female bodies. Thes diferent are called sex characteristic:
PUBERTY
– During puberty Boys:
Voice gets deeper
His muscle get larger and his shoulder get wider
Body hair grows under his arms on his chest and in the pubic area, facial hair also grows on his face
–During puberty girls:
Breast get larger
Her body get larger and her hips get wider
Body hair grows under her arms and in her pubic area
HUMAN REPRODUCTION
These are two types of human reproduction cells these female egg cell (ovum) and the male sperm cell(spermatoozon)
Female reproductive system:
Produce egg cells in the ovaries.
Male reproductive system
Produce sperm cells in the testicles.
THE CELLS
This is a sperm cell
This is a egg cell
And all this produces a baby
We are going to talk about:
-HUMAN REPRODUCTION
-THE FEMALE REPRODUCTIVE SYSTEM
-THE MALE REPRODUCTIVE SYSTEM
-FERTILISATION, PREGNANCY AND BIRTH
In 1920 the economy grew thank to the cars.
Right now the economy avances with the shops , jobs…..
But we have to now that the economy only GROW if we buy things ….this depents about the consumer.
This is called OBSOLENCE PROGRAME.
