Final answer:
Option (A), (The reproductive system encompasses the gonads, ducts, accessory glands and external genitalia involved in reproduction.
Step-by-step explanation:
The reproductive system includes various organs and structures that work together for the purpose of reproduction. The components of the reproductive system typically include:
- Gonads (testes in males and ovaries in females) which produce gametes (sperm and eggs respectively) and sex hormones.
- Ducts such as the vas deferens in males and the Fallopian tubes in females, which transport gametes.
- Accessory glands and organs like the seminal vesicles and prostate gland in males, and the Bartholin's glands in females, that secrete fluids to support gametes.
- External genitalia, such as the p_enis in males and the vulva in females, which play a role in the intercourse process.
Mammary glands, while important for the nourishment of offspring post-birth, are not considered part of the reproductive system directly since they do not participate in the production or fertilization of gametes or the carrying of a fetus. Therefore, the correct answer to the question 'The reproductive system does not include' would be: A. Mammary glands.
