About

HUMAN150 is a free, interactive atlas that shows how the human body changes from the first month of life to 150 years: height and proportions, bones and growth plates, muscles, organs, teeth, and the habits that shape them.

What you can do

• Drag the age slider and watch the body, teeth and body measurements change.
• Look beneath the skin: muscles, organs and skeleton, from the front and the back, and tap any part to learn about it.
• See how pregnancy and the time after birth change a mother’s body.
• Check BMI, healthy weight, daily water, energy and protein, and a WHO growth chart for children.
• Explore how smoking, alcohol, drugs and food habits affect the lungs, liver and lifespan estimates.
• Test yourself with the quiz, and install the app on your phone to use it offline.

Sources and approach

Growth values use the WHO child growth standards and growth references. Nutrition figures follow Indian (ICMR-NIN) and WHO guidance. Illustrations are simplified for learning and are not a substitute for a real anatomy textbook.

Important

HUMAN150 is made for education. Calculators and estimates (BMI, water, calories, lifespan) are rough guides based on population averages and cannot diagnose, treat or predict anything about one person. Always talk to a doctor about your health.
