Oviduct entrance. Coloured scanning electron micrograph (SEM) showing the dark entrance into one of the oviducts from the uterus. The inner wall of the uterus, the endometrium (seen here), is made up of many oval epithelial cells. The oviduct, or fallopian tube, is one of the tubes down which the egg travels from the ovary. The endometrium builds up during the menstrual cycle in readiness for a fertilized egg. Unless the woman does become pregnant the tissue layer is shed at the end of the cycle. Magnification: x75 at 6x4.5cm, x88 at 6x7cm size.
