Nursigo · Anatomy essentials
See the anatomy.
Make the connection.
Turn structures into understanding with focused organ exploration, short study notes and free knowledge checks. Start with an illustration, then open 3D when you want a closer look.
Cardiovascular · Visual study
Understand the heart
Connect the four chambers to pulmonary and systemic circulation.
Optional 3D download: 0.4 MB. Study notes and questions work with the illustration too.
Right and left always refer to the person, not the viewer.
Choose a structure
Read its role below. Open 3D to isolate it in the model.
Start with the whole organ
Connect the four chambers to pulmonary and systemic circulation.
Trace the circulation
- 1. Body
- 2. Right atrium
- 3. Right ventricle
- 4. Lungs
- 5. Left atrium
- 6. Left ventricle
- 7. Body
Exam connection
Name an artery by the direction of flow: away from the heart. Pulmonary arteries carry oxygen-poor blood, so colour alone is not a reliable definition.
