Description: The uterus is a female reproductive organ found in mammals, where conception and gestation of offspring occur. This organ has a muscular and elastic structure that allows it to expand during pregnancy. Its primary function is to provide a suitable environment for the development of the embryo and, subsequently, the fetus. The uterus is lined with a mucous membrane called the endometrium, which thickens and prepares for the implantation of the fertilized egg. If fertilization does not occur, the endometrium sheds during the menstrual cycle. The uterus also plays a crucial role in childbirth, contracting to expel the baby at the end of pregnancy. Its shape and size can vary among different species, but in humans, the uterus is pear-shaped and located in the pelvis, between the bladder and rectum. The health of the uterus is essential for fertility and reproductive well-being in women, and various conditions can affect its function, such as fibroids, endometriosis, or cancer. In summary, the uterus is a vital organ in mammalian reproduction, essential for the continuity of species and the development of life.
