Where is the oviduct

The oviduct is lined with ciliated cells. Every month, an ovum egg develops and becomes mature, and is released from an ovary. The cilia waft the ovum along inside the oviduct and into the uterus.

The uterus is a muscular bag with a soft lining. Test Your Vocabulary. Test your vocabulary with our question quiz! Love words? Need even more definitions? Merriam-Webster's Words of the Week - Oct.

Compare fallopian tube. See ovi- , duct. On the surface of every egg yolk there can be seen a tiny, whitish spot called the blastodisc. This contains a single female cell. If sperm is present when a yolk enters the infundibulum, a single sperm penetrates the blastodisc, fertilizing it and the blastodisc becomes a blastoderm. Technically, the blastoderm is the true egg. Shortly after fertilization, the blastoderm begins to divide into 2, 4, 8 and more cells.

The first stages of embryonic development have begun and continue until the egg is laid. Development then subsides until the egg is incubated. When sperm and ova unite, this process is called fertilization. After fertilization, the egg can develop and become a chick. Only fertilized eggs grow into chicks. The chicks grow and become adult birds. The oviduct is a tube like organ lying along the backbone between the ovary and the tail.
