Century Dictionary and Cyclopedia
    • n oviduct The excretory duct of the female genital gland, or female gonaduct; a passage for the ovum or egg from the ovary of an animal: chiefly applied to such a structure in an oviparous animal, not differentiated into Fallopian tube, womb, and vagina. An oviduct exists in most vertebrates, and is usually paired, there being one to each ovary, but often single, the duct of one or the other side remaining undeveloped, as in birds. When well formed, as in birds and other animals which lay large eggs to be hatched outside the body, the oviduct is a muscuiomembranous tube or canal, of which one end is in relation with or applied to the ovary, and the other debouches in the cloaca, the tube being held in place by a special mesentery or mesometrium. In the course of the oviduct its mucous membrane acquires special characteristics, and secretes different substances; so that the ovum, escaping from the ovary as a ball of yellow yolk, becomes successively coated with white albumen, with a soft egg-pod, and finally, as in birds, with a hard chalky shell. The oviducts of the lowest mammals, which are oviparous, are of similar character; but in most mammals the pair of oviducts coalesce in the greater part of their length, whence result a single vagina and womb, with a pair of Fallopian tubes or oviducts in a restricted sense. A womb or uterus is simply a specialized part of an oviduct, where the ovum is detained long enough to be developed into a fetus and born alive. The oviducts of invertebrates, where any exist, are as diverse in character as the ovaries. See ovary, and cuts under Dendrocæla, Dibranchiata, Epizoa, and germarium.
