Sex can Wait- Lesson 10 – Female
Reproductive System
Transparency 10A
Cervix
• The narrow, lower end of the uterus that
opens into the vagina
• Sometimes called the “neck” of the womb
because of its pear shape
Cilia
• Tiny hair-like projections on the inside of
the fallopian tubes
• The sweeping motion of the cilia move the
egg through the fallopian tube to the
uterus
Conception
• The beginning of new life, marked by
fertilization of an ovum by a sperm
Fallopian tubes
• These narrow tubes are the passageways
from the ovaries to the uterus and the
place where the male’s sperm can fertilize
the female’s ovum
• The fertilized egg or ovum will implant
itself in the lining of the uterus and develop
into a fetus
Fertilization
• The moment an egg (ovum) and a sperm
unite
• Generally fertilization takes place in the
fallopian tubes
Fetus
• The term used to refer to the unborn child
from the ninth week of pregnancy
Follicle
• A capsule in which an ovum or egg cell
develops within the ovary
• When the ovum is mature, it bursts
through the follicle and starts its trip down
the fallopian tube to the uterus
Hymen
• The thin connective membrane covering
all or part of the opening of the vagina
Labia
• Soft, liplike folds of tissue that surroungd
the other sex organs
• Labia majora- outer folds, protect the more
sensitive parts of the vulva;
• Labia minora – inner folds surround the
vaginal opening
Menarche
• The first menstrual period of a female;
begins during puperty
Menstruation
• The phase of the menstrual cycle in which the
thick inner lining of the uterus sloughs off andis
discharged, along with the unfertilized egg,
through the vagina
• This process occurs at about monthly interals if
an egg is not fertilized by a sperm
• Also called “period”
Mons Pubis
• The soft, fatty tissue over the pubic bone
that becomes covered with hair at puberty
Ovaries
• The glands which produce the females
eggs and sex hormone (estrogen)
• Female born with about 400,000 eggs
• After puberty, one egg each month
develops in a capsule called a follicle
inside the ovary
• When egg is mature, it is released from
the ovary into the fallopian tube
• This is called ovulation
Ovum
• The egg cell produced in the ovary of a
female
• It is about the size of a grain of sand
Ovulation
• The release of a mature egg from the
follicle of an ovary
• This happens about once month from the
onset of puberty
Uterus
• The pear shaped, hollow organ in which
the baby develops
• The uterus is muscular and can stretch as
the fetus grows bigger and needs more
room
• The uterus is also called the womb
Vagina
• The tunnel-like structure through which
menstrual blood and babies leave the
female body
Vulva
• The name for the external female sex
organs
Menstrual cycle
• Shedding of the uterine lining through the
vagina, lasting anywhere from 3 to 7 days
• The first day of menstrual flow is
considered the beginning of the menstrual
cycle
• 28 day cycle is average, a 21 to 30 day
cycle may occur
Menstrual cycle
• PMS – Premenstrual syndrome –
produced by hormone changes in the body
– can occur 10 days before mensruation
• Fatigue, anxiety, irritability, a feeling of
puffiness, headache, depression, craving
sweets
• Exercise, eliminating caffeine,
recommended
Menstrual cycle
• Follicle stimulating hormone helps mature
ovum(egg) and releases estrogen which
causes thickening of endometrium if egg is
fertilized it will implant in endometruim if
egg not fertilized, then egg and
endometrium will slough off and pass
during menstrual cycle
