What part of the reproductive tract is responsible for releasing eggs in hens?

The oviduct is the part of the reproductive tract responsible for releasing eggs in hens. This structure plays a crucial role in the reproductive process. The oviduct consists of several sections, including the infundibulum, magnum, isthmus, uterus (shell gland), and vagina. Once the yolk is released from the ovary, it enters the oviduct where it is surrounded by layers of albumen (egg white), membranes, and eventually a shell.

The oviduct's function is vital, as it not only transports the egg but also facilitates the formation of the egg components. Once the egg is fully developed within the oviduct, it is then expelled through the vagina and cloaca during the laying process. Understanding the anatomy and function of the oviduct is fundamental for poultry management and reproductive health.
