Bruises are not lethal because localized extravasated blood is reabsorbed safely
Bruises and localized hemorrhages are typically non-lethal because macrophages and microglia actively phagocytose and safely reabsorb the extravasated blood products.
The claim states that bruises are not lethal because localized extravasated blood is reabsorbed safely via erythrophagocytosis and related clearance mechanisms. Multiple retrieved papers confirm that macrophages and other phagocytic cells efficiently clear extravasated red blood cells and breakdown products, preventing major systemic toxicity under normal physiological conditions. Therefore, the evidence firmly supports the claim.

Demonstrates that enhancing macrophage erythrophagocytosis promotes safe hematoma clearance and tissue recovery.
