PRACTICE TIME! as of a blood vessel or an intestine

Let’s see how you do!


Name this tissue l.jpg
Name this tissue. as of a blood vessel or an intestine


Simple cuboidal epithelium28 l.jpg

Simple Cuboidal Epithelium as of a blood vessel or an intestine

Found where? Can you identify the lumen? Apical and basement membrane?


Name this tissue29 l.jpg
Name this tissue as of a blood vessel or an intestine


Stratified squamous epithelium30 l.jpg

Stratified Squamous Epithelium as of a blood vessel or an intestine

Where in the body is this found? Can you find the lumen/apical surface/basement membrane? What is found under the basement membrane?


Name this tissue31 l.jpg
Name this tissue as of a blood vessel or an intestine
