👉 Peridea is a type of reproductive organ in the human body, typically found at the base or apex of the uterus and is responsible for fertilization of an egg. It plays a crucial role in the process by which a sperm cell enters the egg, facilitating its transfer to the developing embryo. Perideas are also involved in the development of the uterine lining, which serves as a barrier against foreign substances and prepares for implantation.
