Are epithelial tissues avascular?
Understand the Problem
The question is asking whether epithelial tissues lack blood vessels. It seeks to clarify the vascularization of epithelial tissues as a key characteristic in biology.
Answer
Epithelial tissue is avascular.
Epithelial tissue is avascular, meaning it does not have blood vessels directly supplying it with nutrients. Instead, nutrients are supplied through diffusion from the underlying connective tissues.
Answer for screen readers
Epithelial tissue is avascular, meaning it does not have blood vessels directly supplying it with nutrients. Instead, nutrients are supplied through diffusion from the underlying connective tissues.
More Information
This avascular nature necessitates that epithelial tissues receive their nutrients and oxygen through diffusion from the underlying connective tissue, which is often highly vascularized.
Tips
A common mistake is assuming that all tissues have direct blood supply. However, avascular tissues like epithelial tissues rely on their adjacent structures for nutrient supply.
