avascular
This term is primarily used in medical and biological contexts to describe tissues or organs that do not contain blood vessels. It carries a neutral, clinical tone and is used to explain how certain body parts, such as the cornea or cartilage, obtain nutrients through diffusion rather than through a direct circulatory system.
In a pathological context, the term often appears in "avascular necrosis," referring to the death of bone tissue due to a lack of blood supply. This specific usage shifts the connotation from a natural biological state to a diseased or injured state.
