 Dr. O'Hare, remember we're going through the whole list of epithelial tissue types. I'm going to be completely honest with you. These two are the least important. So we're going to cover simple and stratified cuboidal in this video. So here we see simple cuboidal epithelial. Remember, simple tells us one layer, cuboidal tells us the shapes of the cells. Primary places you're going to see these are going to be lining your kidney tubules, which we'll cover way later, and the ducts of some of your glands. So they're responsible for absorption, secretion, and those two key places. Here you see another picture. So you see a single layer of these cuboid or square cubed shaped cells. And then the duct or the tube itself would be there on the inside moving some sort of material. And then we have your stratified cuboidal epithelium. So remember stratified, think protection. So a little bit more protection here. These are pretty rare. Some of your sweat glands are going to have stratified cuboidal epithelium, and then your mammary glands as well. So those are the key examples. And again, not much else to say there, but I do want you to know what simple and stratified cuboidal, at least what they look like. I hope this helps. Have a wonderful day. Be blessed.
