Vejcovody

Vejcovody is a Czech word that translates to "egg carriers" or "egg ducts." In a biological context, it refers to the oviducts in female animals, including humans. The oviduct is a tube that connects the ovary to the uterus. Its primary function is to transport the egg from the ovary to the uterus, where it can be fertilized by sperm.

The oviduct is typically lined with cilia, which are tiny hair-like structures that beat rhythmically to propel the egg along the tube. Fertilization usually occurs within the oviduct. After ovulation, the egg is released from the ovary and enters the oviduct. If sperm are present, they can travel up the oviduct and fertilize the egg. The fertilized egg, now called a zygote, then continues its journey to the uterus for implantation and development.

In poultry, the term vejcovody also refers to the oviduct of hens. This is where the egg is formed. After ovulation, the yolk enters the oviduct, and as it travels through different sections, the albumen (egg white), membranes, and finally the shell are added. The entire process of egg formation can take over 24 hours. The structure and function of the oviduct are crucial for reproduction in many species.
