Blood vessels of human oviduct. Coloured Scanning Electron Micrograph (SEM) of a vascular corrosion cast of blood vessels on the surface of the human oviduct. Tissue around the blood vessels has been removed. Large external veins (blue) are visible, with branches of the tubal artery (pink) seen. A bed of fine capillaries is positioned beneath the larger blood vessels. The oviduct or Fallopian tube is the channel which conducts the female egg from the ovary to the womb, and in which the egg is usually fertilized. Here, the oviduct is highly vascularised 24 hours after an egg was released at ovulation. Magnification: x15 at 6x7cm size.
