Which system enables procreation?

• A. Reproductive System
• B. Cardiovascular System
• C. Lymphatic System
• D. Endocrine System

Answer: (A)

Procreation is enabled by the Reproductive System. This system houses the gonads—ovaries in females and testes in males—that produce the gametes (eggs and sperm) and includes the ducts and organs needed for fertilization, implantation, and birth. It also uses sex hormones to regulate puberty, the menstrual cycle or spermatogenesis, and pregnancy, coordinating the steps that lead to offspring. While other systems support body function or hormone regulation, they do not directly provide the means to create a new organism, which is why this system is the correct choice.
