Friable tissue is characterized by being delicate and easily broken. This designation applies to tissue types that tend to crumble or disintegrate under minimal stress or pressure, making them more vulnerable to damage. In a medical or biological context, friable tissue often refers to certain types of lesions, tumors, or even areas of inflammation that may be soft, weak, and prone to hemorrhage or injury.

Understanding the properties of friable tissue is important in various practical applications, such as surgery or wound care, where careful handling is necessary to avoid further damage. The other characteristics noted in the options do not match the definition of friable tissue. For instance, being very strong and resilient or heavy and dense would imply a robustness that contradicts the inherent fragility associated with friable tissue. Similarly, resistance to tearing suggests a degree of toughness that friable tissue does not possess. Therefore, the defining characteristic of friable tissue is indeed its delicacy and susceptibility to breakage.
