Final answer:
The term that refers to the duct extending from the ovary to the uterus, which conveys an egg or conceptus to the uterus, is the Fallopian tube, also known as an oviduct.
Step-by-step explanation:
The duct that extends from the ovary to the uterus and conveys an egg or conceptus to the uterus is known as the Fallopian tube or oviduct. These uterine tubes are muscular tubes that facilitate transport of an ovulated oocyte from the ovary area to the uterus. The structure of the fallopian tubes includes finger-like projections called fimbriae at their ovarian ends, which guide the ovulated eggs into the tubes. Inside, cilia and smooth muscle contractions work together to move the egg toward the uterus. If fertilization occurs, it most commonly happens within the fallopian tube before the egg continues its journey to the uterus. The fallopian tubes play a crucial role in the reproductive process by allowing for the meeting of sperm and egg, leading to potential fertilization.
