Anatomy · Virtual lab

3D human anatomy. Organ by organ.

Spread your hands and the body opens: the skin parts into two halves and the organs lay out like a page of an anatomy atlas. Pick any of them up, turn it, and put it back where it belongs.

01 / 06Human body

First the whole body, then every part of it.

Assembled, the organs show through the skin. Take it apart and they lay out around the spine.

  1. Spread your hands. The skin opens into two halves and the organs separate: the spine in the middle, the spinal cord to the left, the aorta to the right.
  2. Read it like an atlas. Organs from the right side of the body appear on the left of the screen, as in a textbook illustration where the body faces you.
  3. Put it back. Bring any organ back to the body and it snaps into place. Or leave it hanging in the air.

02 / 06What's inside

24 parts, from the brain to the pelvis.

The parts list is grouped by body system, as in a textbook. Pinch a group to show it on its own, close up.

Skin
left and right halves
Nervous system
left and right brain hemispheres, eyes, spinal cord
Respiratory system
trachea and bronchi, left and right lungs
Circulatory system
heart, aorta and inferior vena cava
Digestive system
liver, gallbladder, pancreas, small intestine, large intestine
Urinary system
left and right kidneys, renal pelvis and ureters, bladder
Immune system
spleen, thymus
Skeleton
spine, pelvis

03 / 06Close-up

Bring an organ up to your eyes.

Pinch an organ, pinch it with your other hand too, and spread your hands. It grows in place and opens full screen, with a card that explains what it is and what it does. In the video: the trachea and bronchi.

  1. Turn it. Pinch anywhere and move your hand. Spread or bring your hands together to zoom.
  2. Look around it. With head-tracked 3D on, move your head and the screen works like a window onto the organ.
  3. Return it. Bring your hands together, or press Back, and the organ goes back into the body.

04 / 06Heart

The structure of the heart in 16 parts.

A separate, larger model of the heart with its great vessels, grouped as in the app: chambers, valves, great vessels and the heart's own vessels.

  1. See inside. In close-up the heart turns semi-transparent, so you can look into a chamber or a valve.
  2. Read the card. Every part comes with a short explanation. The left ventricle, for example, is the main pump: its wall is the thickest in the heart, about 1 cm.
Chambers
right and left atria, right and left ventricles, interventricular septum
Valves
tricuspid, mitral, aortic and pulmonary valves, papillary muscles
Great vessels
aorta, pulmonary trunk and arteries, pulmonary veins, superior vena cava
Heart's own vessels
coronary arteries, cardiac veins

05 / 06Data source

Built on real anatomical data.

The body and heart models come from the 3D Reference Organ Set of the Human Reference Atlas (HuBMAP) by Kristen Browne and Heidi Schlehlein, based on Visible Human Male data from the US National Library of Medicine. For M2 the meshes are simplified and split into parts.

06 / 06Questions

Questions and answers.

Which organs are in the 3D body?

24 parts: the skin in two halves, the left and right brain hemispheres, eyes, spinal cord, trachea and bronchi, left and right lungs, heart, aorta and inferior vena cava, liver, gallbladder, pancreas, small and large intestine, left and right kidneys, renal pelvis and ureters, bladder, spleen, thymus, spine and pelvis.

What is not in the model yet?

The current model has no stomach, esophagus, ribs or skull, and no muscles or bones of the arms and legs. The reproductive system is not included.

Can I study the structure of the heart?

Yes. A separate heart model comes apart into 16 parts: four chambers, the septum, four valves, the papillary muscles, the aorta, pulmonary trunk, pulmonary veins, superior vena cava, coronary arteries and cardiac veins. In close-up it turns semi-transparent, so you can look inside a chamber or a valve.

Where does the anatomical data come from?

From the 3D Reference Organ Set of the Human Reference Atlas (HuBMAP), based on Visible Human Male data from the US National Library of Medicine and licensed under CC BY 4.0.

Is it suitable for medical students and school biology?

Yes. M2 runs in the browser on ordinary computers with a webcam. Universities can order custom models, such as a specific organ system, visible only to them, and start with a pilot in one class.

Do I need a VR headset?

No. A computer or laptop with a webcam and Chrome or another Chromium-based browser, such as Edge, is enough. There is nothing to install, and camera video never leaves your device.

For schools and universities

Bring 3D anatomy to your class.

M2 runs in the browser on computers you already have. Start with a pilot in one class, and order custom models for your course, visible only to your institution.
