Which system is associated with fertilization and birth processes?

• A. Reproductive System
• B. Nervous System
• C. Integumentary System
• D. Urinary System

Answer: (A)

Fertilization and birth are functions of the reproductive system. This system includes the organs that produce and transport gametes and support offspring development, such as ovaries and testes, along with the ducts and structures like the fallopian tubes, uterus, and vagina in females or the penis, vas deferens, and related parts in males. Fertilization occurs when a sperm meets an egg in the female reproductive tract, forming a zygote that can develop into a pregnancy, which then culminates in birth through labor and delivery. While the nervous system, integumentary system, and urinary system play important roles in overall health and bodily functions, they do not govern the direct processes of fertilization and birth.
