reproductivesystem/
The reproductive system allows for the production of offspring and the continuation of human life.
Sexual reproduction
Reproduction in which two sex cells join to form a unique individual.
Puberty
The time of life when sex organs become mature.
Hey Tim, what’s puberty?

Let’s ask Tim and Molby

Now let’s get the anatomy of males reproductive system
Testes- make the sperm and testosterone.
TestosteroneThe main hormone produced by the testes that controls the development of physical characteristics in mature men.
Sperm
Sex cell produced by a male.
Vas deferens
The tube where sperm is mixed with fluids to make semen.
Epididymis
Tube containing sperm attached to a testicle: a coiled tube attached to the back and upper side of the testicle that stores sperm and is connected to the vas deferens.
Seminiferous tubules
One of two or three twisted, curved tubules in each lobule of the testis in which spermatozoa develop.
Semen
A mixture of sperm and fluids.
Penis
The male reproductive organ that transfers semen into the female’s body during sexual intercourse.
Female reproductive system
Ovaries- produces eggs.
Egg
Sex cell produced by a female.
A mass of amphibian eggs
OvulationThe process in which a developed egg is ejected through the ovary wall.
Menstruation
The monthly flow of blood from the uterus beginning at puberty in girls and other female primates.
Period. Do you mean like a punctuation mark? Let’s ask Tim.

Fallopian tube
The tube that leads from an ovary to the uterus.
Uterus
Female organ where a zygote grows and develops.
Vagina
The passageway that receives sperm during sexual intercourse.
Progesterone
a hormone, that prepares the uterus for the fertilized ovum and maintains pregnancy.
Estrogen
Hormones produced chiefly by the ovaries and the development of female secondary sex characteristics.
Cervix
Lower end of the uterus that extends into the vagina.
Internal fertilization
Fertilization of an egg by sperm that occurs inside the body of the female.
Amnion
A thin, tough, membranous sac that encloses the embryo or fetus of a mammal, bird, or reptile.
Amniotic fluid
the watery fluid in the amnion, in which the embryo is suspended.
Now let’s see the baby film

Zygote
A fertilized egg.
Implantation
The process in which an embryo imbeds itself in the lining of the uterus.
Placenta
An organ that provides a developing fetus with nutrients and oxygen from the mother.
Embryo
An organism in the earliest stage of development.
Fetus
An embryo during the later stages of development with the uterus.
Umbilical cord
A cord that connects the embryo to the placenta.
