Reproductive System

It works together with the endocrine system.

To produce the gametes or sex cells.

Will give rise to a new being.

MADE UP

Gonads (ovaries and testes)

Form

Gametes and house the gametes

Ducts and organs to transport

Accessory glands

MADE UP

Internal genital organs

Ovaries

Fallopian tubes

Uterus

Vagina

External genitalia

Vulva

Pubis mound

Labia majora

Labia minora

Clitoris

Vestibule

Mammary glands

ORGANS

Ovaries

Size

Of an almond

Responsible

To produce oocytes

Secrete hormones

Estrogens

Progesterone

Amount

Girl is born

2 million oocytes

At puberty

40 thousand

Only

400 will mature and be expelled.

Fallopian tubes

Tubular organs 10 cm long

On its way through the tubes

The oocyte can be fertilized

Is when it receives the name of ovum

The time it takes for the oocyte from ovulation

To reach the uterus

6 to 7 days

Uterus

Inverted pear-shape organ.

Consists of 3 portions

The upper or fund

The fallopian tubes flow

The body

The fertilized ovum is implanted-

The lower or cervix

Continues with the vagina.

Functions

Implantation of the ovum

Allow pregnancy and delivery

Vagina

Tubular organ 10 cm long

That acts as an

Outlet for menstrual flow.

A receptacle for the penis during intercourse.

Birth canal.

Vulva

Includes external genitalia

Pubic mound

Labia majora

Labia minora

Clitoris

Vestibule

Mammary glands

Paired organs

Located

In the anterior part of the torax.

Are the alveolar sacs

Produce milk

Transport it through ducts until it ends in the nipple.

Laction

Regulated

By the prolactin and oxytocin hormones

MENSTRUAL CYCLE

Regulated by hormones

Menstrual phase

Levels of estrogen and progesterone decrease.

Causing the detachment of the endometrium.

Lasts from 1 to 5 days

Pre-ovulatory phase

In the uterus, the endometrium begins to develop again.

Thanks to the secretion of estrogens.

Ovulation

Estrogen production reaches its peak.

This triggers the production of LH in the pituitary.

Causing the rupture of the follicle in the ovary releasing the oocyte.

Postovulatory phase

Ovary rupture

Corpus luteum is formed

Begins to produce estrogens and progesterone

will provide nutrition in the event of fertilization

No fertilization

Hormones decrease

Menstruation occurs

ORGANS

Testicles

Located

In the scrotal bags

Inside

Seminiferous tubules

Sperm develop

Produce

Testosterone

Ducts of the male reproductive system

Function

Protect and conduct sperm

Epididymis

Substance are produced for the maturation of sperm.

Vas deferens

Drives sperm

Ejaculatory duct

Urethra

Semen

Made up

Sperm

Accessory gland secretion

Accesory glands

Secrete the fluid

where the sperm will move

Seminal vesicles

Provide 60% of the semen.

Prostate

Provides 25% of the semen volume.

Bulbourethral glands

Produce

Viscous and alkaline liquid.

Penis

Copulatory organ

Contains
