Urethra
External urethral orifice

Sagittal section showing female reproductive organs
The
infundibulum
is the funnel-shaped
end of the uterine tube that lies near
the ovary but is open to the pelvic
cavity. Finger-like projections called
fimbriae catch the egg released from
the ovary and direct it into the tube.
Broad ligament
The
vagina
, or birth canal, is a
muscular tube that extends from the
uterine cervix to the outside. It
receives the male’s penis during
intercourse and is the pathway that
the fetus traverses during labor.
The
uterine (fallopian) tubes
carry
eggs from the ovaries to the uterus.
Fertilization usually occurs here.
Sagittal
plane
Coccyx
Rectum
Anus
The
ovaries
(female gonads) produce
eggs and hormones (
progesterone
,
estrogen
,
inhibin
,
relaxin
).
The
uterus
receives and
implants the fertilized egg and
houses the developing fetus
during pregnancy and labor.
Round ligament
The
cervix
is the narrow portion of
the uterus opening into the vagina.
Urinary bladder
Pubic symphysis
The
mons pubis
is elevated adipose
tissue covered by skin and pubic
hair that cushions the pubic
symphysis.
Clitoris
The
labia
are longitudinal folds of skin
extending down from the mons pubis
that cover the vagina and urethral
openings:
• Labia minora contains oil glands.
• Labia majora contains adipose
tissue, oil glands, and pubic hair.
