Figure 19- 8 Oogenesis in the ovary.
The Uterine or Fallopian Tubes
The female body contains two uterine (YOO-ter-in) or
fallopian (fah-LOH-pee-an) tubes that transport the ova
from the ovaries to the uterus (see Figure 19-6). There is a
funnel-shaped open end to each tube called the in-
fundibulum (in-fun-DIB-yoo-lum). This lies close to an
ovary but does not attach to it. The infundibulum is
surrounded by a fringe of finger-like projections called the
fimbriae (FIM-bree-ee) that partially surround an ovary.
Approximately once a month an ovum ruptures from the
surface of an ovary near the infundibulum of the uterine
tube, a process called ovulation.
The ovum is swept by ciliary action of the epithelium
of the infundibulum and by the waving fimbriae, which
create a current that carries the egg into the uterine
