An egg cell takes a slow trip down a fallopian tube. Peg cells line the tube and make a fluid that helps it along the way.

The two fallopian tubes connect the ovaries, where egg cells are kept, to the uterus, or womb.
The inside of each tube is lined with two main kinds of cells. Ciliated cells have tiny moving hairs. Peg cells have no hairs. They are narrower, and squeeze in between, like pegs.
Press Release fluid on the 3D model to watch the peg cells let out their fluid.
Peg cells are secretory cells. That means they make and release something. They make the fluid that fills the tube.
An egg cell takes a few days to travel down the fallopian tube to the uterus.
