When we are children, boys and girls have a very similar body; but when we enter the puberty our bodies begin to change.Let's going to discover how it happens: |
Puberty is the time in which a child's sexual and physical characteristics mature. It occurs due to hormone changes.
Adolescence is the period between puberty and adulthood. It is a time of psychological maduration, which a person becomes "adult-like" in behaviour. Adolescence is considered to be the period between ages 13 and 19.
Some information
The exact age a child enters puberty depends on a number of different things, such as genes, nutrition, and gender. During puberty, endocrine glands produce hormones that cause body changes and the development of secondary sexual characteristics.
In girls, the ovaries begin to increase production of estrogen and other female hormones.
In boys, the testicles increase production of testosterone.
The adrenal glands produce hormones that cause increased armpit sweating, body odour, acne, and armpit and pubic hair.
