Study GuideBiology–Reproduction1. Human ReproductionReproduction is a vital process because it allows a species to continue from one generation to thenext. In humans, reproduction depends on the proper working of the male and femalereproductivesystems. Each system has specific roles, but they work together toward the same goal—creating newlife.1.1 The Role of the Reproductive SystemsThe main job of the reproductive systems is to producegametes, which are reproductive cells.•In males, the gametes aresperm.•In females, the gametes areeggs.These cells are specially designed for reproduction and contain half the usual number ofchromosomes. Before fertilization can happen, the reproductive systems also prepare these gametesso they are ready to function properly.1.2 The Male Reproductive SystemThe male reproductive system produces sperm and delivers them into the female reproductive tract.This delivery is essential because fertilization can only occur when a spermmeets an egg. Thesystem is built to protect, nourish, and transport sperm efficiently.1.3 The Female Reproductive SystemThe female reproductive organs have several important roles. They receive the sperm and allowfertilization to occur. After fertilization, they provide nourishment and a safe environment for thefertilized egg. This environment supports the developing embryo as it grows into a fetus andeventually into a baby.Preview Mode
