Men as well as woman share most of the systems that make the maintenance and development of life possible. However, there is a group of organs and tissues that present notable differences between both genders. They are the ones in charge of reproduction, meaning, the ones that manufacture sexual cells, allow sexual relations, fertilization and, in the case of women, to house the new being until its birth. They are two totally different systems, but whose joint action perpetuates the human species. The female reproductive system is made up of a series of organs that are mostly housed un the pelvic area. It also has an external part, in plain sight, called vulva, made up of different accessory structures that participate more directly in the sexual encounter and protection of the internal organs.
