The journey of human development starts from a tiny cell and grows into a fully formed adult. Here’s a simple breakdown of each stage:
Zygote (0-2 weeks): This is the very first stage. It begins when a sperm fertilizes an egg. A single cell is formed, and it starts to divide quickly.
Embryo (2-8 weeks): In this stage, the major organs begin to develop. About 21 days after fertilization, the heart starts to beat, and the body starts forming important parts.
Fetus (9 weeks to birth): The body keeps growing and getting ready for birth. Around week 12, it's possible to tell whether it’s a boy or a girl. By week 24, the fetus can survive outside the mother’s body.
Infancy (0-1 year): Babies go through a lot of growth during this year. They usually triple their birth weight!
Childhood (1-12 years): In childhood, growth continues at a steady pace. Kids grow about 2.5 inches each year on average.
Adolescence (12-18 years): This is the teenage years when kids go through puberty. During this time, girls might grow about 4 inches per year, while boys might grow about 5 inches.
Adulthood (18 years and beyond): In adulthood, people reach their full physical growth. The strongest bones are usually developed by the age of 30.
Each stage has its own special changes and growth patterns that help us become who we are!
