Document Summary
The urethra is the tube that is used by urine and semen but not at the same time. The urethra and the bladder are separate from the vagina and the uterus. Within the ovaries are what we call follicles that will develop at different times and go through different stages at different time from infancy to menopause. Follicles produce the hormones so they respond to lh and fsh that will produce estrogen for an example. They also have the oocyte that will be developing. The fallopian tube will transport an oocyte from the ovaries if it is released to the uterus. As the hormones are changing and getting closer to the ovulation time, the fallopian tube sits right over the top of the ovaries. The fimbriae which are finger like structures can move. They sweep fluid up through the fallopian tube and will increase this activity during ovulation. The oocyte is only viable for 24-48 hours.
