This document provides information about the female reproductive system. It describes both the external organs, such as the vulva, labia, clitoris, and vestibule, and the internal organs, including the vagina, uterus, fallopian tubes, and ovaries. It also discusses the role of hormones in reproduction and development of the embryo from fertilization through organogenesis. The document concludes by describing the accessory breast organ and the role of oxytocin in parturition.

16. The Female reproductive
system provides suitable
environment for the
development of embryo
until delivery.

17. Provides suitable
environment
• External organs
• Internal organs
• Role of hormones

18. External
Organs

19. 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.

20. Labia Majora
• two
prominent,
rounded
folds of skin.

21. Pudendal cleft
• is the space
between
two Labia
Majora
Labia Minora
• pair of thin,
longitudinal
folds that
occupies
pudendal
cleft

22. Prepuce
• where
the two
Labia
Minora
unite
over
clitoris
to form a
fold skin

23. 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.

24. B. Vestibule-split between labia
minora
Hymen
• thin
covering
of mucous
membrane
of the
vaginal
opening

26. Vaginal Orifice
• occupies 2/3
of the
vestibule
• contains
Bartholin’s
gland that
elaborates
mucous
secretion that
acts as a
lubricant
during sexual
intercourse

27. Urethral orifice
• 4 to 6 mm in
diameter
• posterior to
clitoris and
anterior to
vaginal orifice
• functions for
discharging
urine

28. Clitoris
• pea-shaped
projection
that is
important in
sexual
excitation of
the female
• contains
nerves,
erectile
tissues and
blood vessels
• Associated
with Penis

29. Female
circumcision
originated in
Egypt (as
observed on
mummies 163
BC) and adapted
by countries
within Middle
East, central
South Africa and
Southeast Asia.

32. Internal
Organs

33. Vagina
• tubular canal
4-6 inches in
length
extending from
vestibule to
uterus;
• vaginal wall
has muscle
layer capable
of constriction
and enormous
dilation;

34. • part of birth
canal and
functions to
receive the
penis during
sexual
intercourse.
• It also allows
menstrual
flow and
childbirth.

35. 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;

36. Parts of the uterus:
• Fundus-superior to the entrance of
uterine tube
• Body-main part of the uterus
• Cervix-narrow part near vagina

39. Ectopic pregnancy

40. Walls of the uterus
• Perimetrium
• Myometrium
• Endometrium

42. 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

43. Parts of fallopian tube
• Isthmus
• Ampulla
• Infundibulum
• Fimbriae

44. Ovaries
• Small ovoid
body (almond
shape).
• is the site for
oogenesis and
production of
female
hormones

45. • 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

47. 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

49. Development of
Embryo• Fertilization
• Early cell division
(cleavage)
• Formation of Germ
layer
(Gastrulation)
• Neurolation
• Organogenesis

57. Parturition
(delivery)
• Accessory organ
(breast)
• Role of Oxytocin

58. Accessory Organ
(Breast)

60. 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.

61. 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).

62. 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.

63. Each lobe possesses a single
lactiferous duct that opens
independently to the surface of
nipple.

64. Lactiferous
sinus
• Small,
spindle
shaped
• Accumulates
milk during
milk
production.

Oxytocin
