Which system produces gametes and hormones?

• A. Produces gametes and hormones
• B. Regulates digestion
• C. Controls breathing
• D. Transports oxygen

Answer: (A)

The reproductive system handles both making gametes and producing key hormones. Gametes are the reproductive cells—sperm in males and eggs in females—formed in the gonads through meiosis. Those same gonads also produce hormones like testosterone, estrogen, and progesterone that regulate sexual development, reproduction, and related processes. The other systems have different primary roles—digestion, breathing, or transporting oxygen—and do not generate gametes, so they don’t fit the description.
