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.

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

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
