THE BODY, CONNECTED

Twelve ways to understand one body.

From the cells beneath your skin to the signals in your brain, discover how each system contributes to life.

CELL → TISSUE → ORGAN → SYSTEM

THE BIG PICTURE

From a tiny cell to a living system.

Cells form tissues, tissues contribute to organs, and organs work together as systems. The human body is a remarkable example of teamwork.

HEALTH CONNECTIONS

What happens when a system needs help?

Explore a few common conditions through simple questions. Each card links to trusted medical information; it is not a diagnosis tool.

PLAY & LEARN

Test yourself, game style.

Three quick games: label the kidney model, match organs to their systems, and beat the clock in System Sprint.

GAME 1 · LABEL IT!

🫘 Label the kidney model

We name a structure — you tap its marker on the real model photo.

Tap Start, then find the named structure.

GAME 2 · ORGAN MATCH

🧩 Match organ → system

Tap an organ, then tap the system it belongs to. Match all 8 pairs.

Choose an organ to begin.

GAME 3 · SYSTEM SPRINT

⏱️ System Sprint — 60 seconds

Read the job description and tap the right system. How many can you get before time runs out?

Press Start when ready.

Best score is kept only on this screen — no pressure.

LEARN BY DISCOVERY

Put your knowledge to the test.

No pressure. Just six thoughtful questions and instant explanations to help ideas stick.

QUESTION 1 OF 60 points

Which organ pumps blood around your body?

Type 2 Diabetes: Your Questions Answered

A complete inquiry-based guide by Mariam Ohanyan, MD — understand it, prevent it, live well. Every chapter begins with a real question and ends with a safe next step. Dedicated to the memory of her father. The full book — all 20 chapters, the 30-day workbook, recipes and meal plans — is PRO content for members.

FREE PREVIEW · CHAPTER 1

“If I eat sugar, does that mean I will get diabetes?”

No. Type 2 diabetes develops through interacting biological and environmental factors, not from one food or one personal choice. The body becomes less responsive to insulin, while the pancreas may gradually become unable to release enough insulin to meet its needs. The result is persistently elevated blood glucose. Family history, age, body-fat distribution, other metabolic conditions, and the environment in which a person lives can influence risk.

Chapter 1 continues with what to observe, how diagnosis really works (HbA1c, fasting glucose, OGTT), and the question to ask at your next appointment — inside PRO.
