layers undergo extensive changes. The perimetrium is a strong, serous membrane that
coats the entire uterine corpus except the lower one fourth and anterior surface where
the bladder is attached.
Figure 1-3. Walls of the uterus.
(1) Location. The vagina is the thin in walled muscular tube about 6 inches
long leading from the uterus to the external genitalia. It is located between the bladder
and the rectum.
(2) Function. The vagina provides the passageway for childbirth and
menstrual flow; it receives the penis and semen during sexual intercourse.
c. Fallopian Tubes (Two).
(1) Location. Each tube is about 4 inches long and extends medially from
each ovary to empty into the superior region of the uterus.
(2) Function. The fallopian tubes transport ovum from the ovaries to the
uterus. There is no contact of fallopian tubes with the ovaries.
(3) Description. The distal end of each fallopian tube is expanded and has
finger-like projections called fimbriae, which partially surround each ovary. When an
oocyte is expelled from the ovary, fimbriae create fluid currents that act to carry the
oocyte into the fallopian tube. Oocyte is carried toward the uterus by combination of
tube peristalsis and cilia, which propel the oocyte forward. The most desirable place for
fertilization is the fallopian tube.
