No. Avascular means that it does not get blood.
Yes, a Venus Flytrap is avascular.
Tissue without capillaries is called avascular tissue. Examples of avascular tissue include:CartilageEpitheliaCorneaLensAll organs contain blood vessels.
All epithelial tissue is avascular
No, hemoglobin is found predominantly in blood. The stratum corneum is avascular, and hemoglobin is not predominant in this skin layer.
