What does ecchymosis do?

Ecchymosis refers to the accumulation of blood beneath the skin due to the rupture of small blood vessels, often resulting from trauma or injury. It appears as a purplish or blue discoloration on the skin and can indicate underlying bleeding. The process involves the breakdown of hemoglobin, leading to color changes as the body reabsorbs the blood. While ecchymosis itself doesn't serve a direct purpose, it can be a visual indicator of injury or underlying health conditions.
