Fallopian tubes (oviducts, fallopian tubes) are located on both sides of the bottom of the uterus. They are two muscle tubes 10-12 cm long, lined inside with a folded mucosa. Each of the fallopian tubes opens into the abdominal cavity in the ovary.

The ventral end of the tube is enlarged and looks like a funnel equipped with fringes. Fimbriae pick up a ripe egg (which emerged into the abdominal cavity of the ovary) and transport it to the tube.

Due to contractions of the muscular apparatus of the fallopian tube, the egg moves to the uterine cavity. The excitability of the muscles of the tube, as well as the nature of their contractions, are directly dependent on the phases of the menstrual cycle.

Fallopian tubes under normal conditions are the place where the spermatozoon fertilizes an ovum. Inside the tube is covered with small cilia, the movement of which along with the contraction of the muscles of the walls accelerates the movement of the egg into the uterus health. sumy. ua.
