Solutions
Epithelial tissue has no blood supply. What is the term for this? - ANS Avascular
Epithelial, because of its avascular nature, depends on this form of passive transport for gas
exchange and nutrients. - ANS Diffusion
What are the five functions of epithelial tissue? Remember PFADS. - ANS Protection, filtration,
absorption, diffusion, and secretion.
What does the first part of an epithelial tissue name tell us? - ANS How many layers it has.
What are the three terms for epithelial tissue layers? - ANS Simple, stratified, and
pseudostratified.
Identify this tissue. - ANS
