What is the primary function of the reproductive system?

To support and protect internal organs
To produce gametes and facilitate the development of offspring
To transport nutrients and oxygen to cells
To communicate messages throughout the body

The correct answer is: To produce gametes and facilitate the development of offspring

The primary function of the reproductive system is to produce gametes, which are the sperm in males and eggs in females, and to facilitate the development of offspring. This system is essential for sexual reproduction, enabling the combination of genetic material from two parents to create a new individual. Through processes such as fertilization, where sperm merges with an egg, and subsequent development of the embryo, the reproductive system ensures the continuation of a species. The other functions, while important in different systems of the body, do not pertain specifically to the main role of reproduction. Supporting and protecting internal organs relates to the skeletal and muscular systems. Transporting nutrients and oxygen is primarily the function of the circulatory system. Communicating messages throughout the body falls under the domain of the nervous system. Thus, the reproductive system distinctly focuses on gamete production and offspring development.
