**Core Concept**
Biomedical waste management is a critical aspect of infection control and environmental protection. Category 7 waste is a specific category of waste that requires special handling and disposal due to its potential to cause harm to humans and the environment.

**Why the Correct Answer is Right**
Category 7 waste includes anatomical waste, which includes human tissues, organs, and body parts.
