In anatomy, the key difference between viscus and viscera is simply one of number: a viscus is a single internal organ, while viscera is the plural form, referring to multiple internal organs.
Viscus vs. Viscera: A Simple Explanation
To put it plainly:
| Term | Definition | Example |
|---|---|---|
| Viscus | A single internal organ. | The stomach is a viscus. |
| Viscera | Multiple internal organs (plural form). | The stomach, intestines, and liver are viscera. |
Examples of Viscera
- The heart
- The lungs
- The liver
- The intestines

- The spleen
Basically, any major organ located within the body cavities (thoracic, abdominal, and pelvic) can be referred to as a viscus.
