Is a scab covering a wound avascular?

Yes, a scab covering a wound is avascular, meaning it does not contain blood vessels. The scab forms as a protective barrier over the wound, composed primarily of dried blood and extracellular matrix components, which helps to prevent infection and facilitate healing. While the underlying tissue may have a blood supply, the scab itself does not, as it is made up of coagulated material.
