Male and Female Reproductive System! Changes in the human body: When a baby begins to grow, the different parts of its body such as the head, arms, legs and chest grow at different rates. For about the first 12 years of its life it goes through a phase of body enlargement and mental development.

These changes prepare the body for sexual reproduction. This phase is known as adolescence. During this phase, certain parts of the body change in appearance and the person also experiences new sensations such as extreme happiness, sadness, anger, insecurity, and so on.
