Takeaways

  • 🌱 Human growth starts from a tiny embryo and goes through various stages influenced by numerous factors, resulting in differences in height, weight, and thinking among individuals.
  • 🤰 The embryonic stage begins with a small egg cell and develops into a baby within the womb, receiving nutrition through the umbilical cord and experiencing growth.
  • 👶 After birth, babies cry loudly due to the change from the warm, dark womb to the new environment, signaling the start of breathing with lungs.
  • 👶🏻 The infancy stage (0-5 years) marks the early growth and development of humans, with rapid physical development, such as crawling, walking, and running.
  • 🗣️ During infancy, communication development occurs through laughter, crying, speaking single words, and eventually full sentences.

  • 👩‍🦳 The adult stage (17-50 years) sees a maturation in thinking, with individuals becoming more rational and wise in their actions.
  • 👵 The elderly stage (over 50 years) is marked by a decline in organ function, such as reduced hearing, slower movements due to stiffness, and decreased resistance to diseases.
