Which is a function of the reproductive system?

• A. Maintenance of sexual characteristics and the perpetuation of our species
• B. Oxygen transport to tissues
• C. Filter toxins from the blood
• D. Regulate blood glucose

Answer: (A)

The reproductive system is responsible for producing sex cells and hormones that drive the development of secondary sexual characteristics and enable conception and birth, helping to perpetuate the species. That combination—maintaining sexual characteristics and enabling reproduction—is what this option captures best. The other choices belong to different systems: oxygen transport to tissues is a circulatory function, filtering toxins from the blood is an excretory/detox role, and regulating blood glucose is mainly an endocrine function involving organs like the pancreas.
