Lungs anatomy in 3D

Beta

Explore the trachea, the bronchial tree and the pulmonary arteries and veins of both lungs, grouped by lobe and by the ten segments of each lung.

Beta

Interactive 3D atlas

Loads about 9 MB of 3D data the first time. Works best on a laptop or a recent phone.

Study the lungs in 3D

Explore the trachea, the bronchial tree and the pulmonary arteries and veins of both lungs, grouped by lobe and by the ten segments of each lung.

Turn and zoom

Drag to rotate, scroll or pinch to zoom, and tap any part to see its name and explanation.

Labels and standard views

Switch labels on or off and jump to front, back, side, top and bottom views, with an orientation cube.

Section cuts

Cut through the structure in transverse, coronal or sagittal planes and slide the cut through it.

Explode and see-through

Pull the parts apart, or make the outer layers faint to see what is inside.

Guided tour

Follow the "Air and blood" tour one step at a time, or press Play and let the camera fly to each part.

Parts in this model

291 named parts, each with the FMA identifier the dataset gives it. Tap a group in the app to show or hide it.

  • Trachea and main bronchi3
  • Segmental bronchial trees98
  • Segmental pulmonary arteries95
  • Segmental pulmonary veins85
  • Pulmonary trunk and arteries3
  • Pulmonary veins7

Guided tour: Air and blood (6 steps)

Each step highlights the parts it talks about. The sentence is quoted word for word from OpenStax Anatomy and Physiology 2e.

  1. 1. Trachea

    The trachea branches into the right and left primary bronchi at the carina.
    OpenStax, 22.1 Bronchial Tree

  2. 2. Main bronchi

    The primary bronchi enter the lungs at the hilum, a concave region where blood vessels, lymphatic vessels, and nerves also enter the lungs.
    OpenStax, 22.1 Bronchial Tree

  3. 3. Segmental bronchial trees

    Each segment receives air from its own tertiary bronchus and is supplied with blood by its own artery.
    OpenStax, 22.2 Gross Anatomy of the Lungs

  4. 4. Pulmonary trunk and arteries

    The pulmonary artery is an artery that arises from the pulmonary trunk and carries deoxygenated, arterial blood to the alveoli.
    OpenStax, 22.2 Blood Supply

  5. 5. Segmental pulmonary arteries

    The pulmonary artery branches multiple times as it follows the bronchi, and each branch becomes progressively smaller in diameter.
    OpenStax, 22.2 Blood Supply

  6. 6. Segmental and pulmonary veins

    Once the blood is oxygenated, it drains from the alveoli by way of multiple pulmonary veins, which exit the lungs through the hilum.
    OpenStax, 22.2 Blood Supply

What this model does not show

BodyParts3D has no meshes for the lung surfaces, fissures or pleura, so they are not shown. Each lobe is shown through the airways and vessels that the dataset assigns to it.

Where the data or the textbook has a gap, the atlas says so instead of filling it in.

Questions

What can I see in the lungs model?

The model has 291 named parts in 6 groups: Trachea and main bronchi, Segmental bronchial trees, Segmental pulmonary arteries, Segmental pulmonary veins, Pulmonary trunk and arteries, Pulmonary veins.

What is the "Air and blood" tour?

It is a guided tour of 6 steps. Each step highlights the parts it describes and shows a sentence quoted from OpenStax Anatomy and Physiology 2e. Press Play to let the camera fly to each step for you.

What is missing from the lungs model?

BodyParts3D has no meshes for the lung surfaces, fissures or pleura, so they are not shown. Each lobe is shown through the airways and vessels that the dataset assigns to it.

Where does the information come from?

The 3D shapes come from the BodyParts3D dataset (and, for the female pelvic region, the Human Reference Atlas). Every explanation is a sentence quoted word for word from the open textbook OpenStax Anatomy and Physiology 2e, with a link to its section.

Can I use it to diagnose or treat anything?

No. The atlas is for learning only. It is a beta version and has not yet been reviewed by an anatomy educator.
