The reproductive system ensures the survival of the species. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for the survival of the individual. An individual may live a long, healthy, and happy life without producing offspring, but if the species is to continue, at least some individuals must produce offspring.
