Female

Reproductive

SystemPart 1

Ibangelio, Laira Joyce P.Rivera, Roland AudreyIII-9 BSE Biology

The Female reproductive

system provides suitable

environment for the

development of embryo

until delivery.

Provides suitable

environment

• External organs

• Internal organs

• Role of hormones

External

Organs

A. Vulva-wrapper or covering (also

known as pudendum)

Mons Pubis

• firm

cushion-like

elevation of

adipose

tissue

covered by

pubic hair

• It is the site

where two

Labia Majora

meet

anteriorly.

Labia Majora

• two

prominent,

rounded

folds of skin.

Pudendal cleft

• is the space

between

two Labia

Majora

Labia Minora

• pair of thin,

longitudinal

folds that

occupies

pudendal

cleft

Prepuce

• where

the two

Labia

Minora

unite

over

clitoris

to form a

fold skin

Clinical

Peritoneum

• is the region

between anus

and vagina

• contains skin

and muscle

that can be

torn during

childbirth.

• Episiotomy is

the incision of

clinical

peritoneum to

avoid tearing.

B. Vestibule-split between labia

minora

Hymen

• thin

covering

of mucous

membrane

of the

vaginal

opening

Vaginal Orifice

• occupies 2/3

of the

vestibule

• contains

Bartholin’s

gland that

elaborates

mucous

secretion that

acts as a

lubricant

during sexual

intercourse

Urethral orifice

• 4 to 6 mm in

diameter

• posterior to

clitoris and

anterior to

vaginal orifice

• functions for

discharging

urine

Clitoris

• pea-shaped

projection

that is

important in

sexual

excitation of

the female

• contains

nerves,

erectile

tissues and

blood vessels

• Associated

with Penis

Female

circumcision originated in

Egypt (as

observed on

mummies 163

BC) and adapted

by countries

within Middle

East, central

South Africa and

Southeast Asia.

InternalOrgans

Vagina

• tubular canal

4-6 inches in

length

extending from

vestibule to

uterus;

• vaginal wall

has muscle

layer capable

of constriction

and enormous

dilation;

• part of birth

canal and

functions to

receive the

penis during

sexual

intercourse.

• It also allows

menstrual

flow and

childbirth.

Uterus/womb

• is as big as a

medium-sized

pear.

• oriented in the

pelvic cavity

with the larger,

rounded part

directed

superiorly.

• It functions for

the implantation

of the fertilized

egg;

Parts of the uterus:• Fundus-superior to the entrance of

uterine tube

• Body-main part of the uterus

• Cervix-narrow part near vagina

Ectopic pregnancy

Walls of the uterus

• Perimetrium

• Myometrium

• Endometrium

Fallopian tube

• named after Italian

anatomist Gabrielle

Fallopio.

• Extends from the area

of ovaries to the

uterus

• Opens directly into

the peritoneal cavity

near each ovary and

receive the oocyte

• The opening of the

uterine tube is

surrounded by long,

thin, process called

fimbriae

Parts of fallopian tube• Isthmus

• Ampulla

• Infundibulum

• Fimbriae

Ovaries

• Small ovoid

body (almond

shape).

• is the site for

oogenesis and

production of

female

hormones

• it is attached to the

mesovarium which

also conducts

blood vessels into

the organ

• The outer layer of

each ovary is

packed with

follicles, each

consisting of

oocyte a partially

developed egg,

surrounded by a

group of support

cells

Role of

HormonesUterus is where the baby is found

during pregnancy, and due to

pregnancy placenta is developed.

Placenta Functions for:

• Barrier

• Immune Protection

• Site of Exchange

• Secretion of

Hormones

Development of

Embryo• Fertilization

• Early cell division

(cleavage)

• Formation of Germ

layer

(Gastrulation)

• Neurolation

• Organogenesis

• Accessory organ

(breast)

• Role of Oxytocin

Accessory Organ

(Breast)

Nipple

• a structure from

which a fluid

emanates. More

specifically, it is

the projection

on

the breasts or u

dder of a

mammal by

which breast

milk is delivered

to a mother's

young.

Areola

• is any small

circular area on

the body coloured

differently from the

surrounding tissue.

• The term is most

commonly used to

describe

the pigmented area

on the

human breast arou

nd

the nipple (areola mammae).

Lobes• Each adult

female

mammary

gland usually

consists of 15-

20 glandular

lobes by a

considerable

amount of

adipose tissue.

• It is primarily

this superficial

fat that gives

the breast its

form.

Each lobe possesses a single

lactiferous duct that opens

independently to the surface of

nipple.

Lactiferous

sinus

• Small,

spindle

shaped

• Accumulates

milk during

milk

production.
