Answer:
A.human reproductive system
Explanation:
-The major function of the reproductive system is to ensure survival of the species. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for survival of the individual. An individual may live a long, healthy, and happy life without producing offspring, but if the species is to continue, at least some individuals must produce offspring.
Within the context of producing offspring, the reproductive system has four functions:
- To produce egg and sperm cells
-To transport and sustain these cells
-To nurture the developing offspring
-To produce hormones
