Question

skin, lung, and blood vessel walls have which tissue characteristic in common?
simple squamous epithelium.
simple columnar epithelium
reticular fibers
elastic fibers

Explanation:

Simple squamous epithelium is a single - layer of flat cells. It is found in the alveoli of the lungs for gas exchange, in the lining of blood vessels (endothelium), and in the serous membranes that line organs like the skin's underlying structures in some aspects. Simple columnar epithelium is more associated with absorption and secretion in organs like the intestines. Reticular fibers form a mesh - like framework in certain tissues. Elastic fibers provide elasticity but are not the common tissue characteristic among these three.
