petevezetékben

A petevezetékben, also known as the oviduct or fallopian tube, is a paired tubular structure in the female reproductive system. It connects the ovary to the uterus. Humans typically have two petevezetékben, one on each side of the uterus. The primary function of the petevezetékben is to transport the ovulated egg from the ovary to the uterus. This transport is facilitated by the rhythmic contractions of the smooth muscle walls of the tube and the action of cilia, tiny hair-like projections that line the inner surface of the petevezetékben. Fertilization, the fusion of sperm and egg, commonly occurs within the petevezetékben. After fertilization, the resulting zygote begins to divide and develops into an early embryo, which is then moved towards the uterus for implantation. The petevezetékben is divided into several sections: the infundibulum, which is funnel-shaped and has finger-like projections called fimbriae that sweep the surface of the ovary to capture the released egg; the ampulla, which is the widest part where fertilization usually takes place; the isthmus, a narrower section connecting to the uterus; and the intramural or uterine part, which passes through the uterine wall. The petevezetékben plays a crucial role in female fertility and reproduction.
