Final answer:
The role of the reproductive system in humans, felines, and canines is to facilitate sexual reproduction and the production of offspring.
Step-by-step explanation:
The role of the reproductive system in humans, felines (cats), and canines (dogs) is to facilitate sexual reproduction and the production of offspring.
In humans, the male reproductive system produces sperm and releases testosterone into the body. The female reproductive system produces eggs and provides a suitable environment for the fertilized egg to develop into a fetus.
In felines and canines, the reproductive systems are similar to humans. The male reproductive system produces sperm and releases hormones like testosterone, while the female reproductive system produces eggs and prepares the body for pregnancy.
