What organ is responsible for the development of the embryo?

The uterus is the organ responsible for the development of the embryo. After fertilization occurs in the fallopian tube, the fertilized egg travels to the uterus, where it implants into the uterine lining. This is a crucial step in the pregnancy process, as the uterus provides a suitable environment for the embryo to grow and develop throughout gestation. It offers nourishment and protection, allowing for the establishment of a placenta which further supports the growing embryo. The uterus expands as the pregnancy progresses, accommodating the developing fetus until birth.

The other options, such as the fallopian tube, ovaries, and cervix, play different roles in reproduction but are not directly responsible for the embryonic development itself. The fallopian tube is where fertilization typically occurs; the ovaries produce the eggs and hormones; and the cervix serves as the opening to the uterus, playing a role during childbirth but not in the nurturing of the embryo.
