Reproductive system


REPRODUCTIVE SYSTEM
-         Our reproductive system allows us to have babies.
-         The female reproductive system produces eggs in the ovaries.
-         The male reproductive system produces sperm in the testicles.
-         When a sperm fertilises an egg the fertilised egg goes to the uterus.
-         It stays there and develops into a baby after nine months.
