I believe Tissue Y is Epithelial Tissue. Would this be correct? Thanks

And the cell?

And the cell?

I am not too sure, I think either goblet cell or cillia.

Partly. What do you notice about this epithelial cell?

That it has lots of cilia.

Goblet cell is correct :smile:

Why do you think this cell does? What does the shape remind you of?

Yes! So you'd need to put both cilliated and epithelial (cell) to get the mark

does it remove mucus and move it away?

Oh okay. That makes sense. So Tissue Y would be ciliated epithelial cell and cell Z would be goblet cell? Thank you:smile:

No problem. :smile: You should be able to think through the function of the goblet cell by thinking about what the cilia (which you've already identified) might be sweeping...

Goblet cell produces the mucus. And it looks like a 2D goblet (that’s how I remembered it). Cilia are the small hair like cells that waft the mucus towards the back of your throat in order for you to swallow the mucus

Thank you, that makes sense now. Would I say tissue Y is ciliated epithelial tissue or a ciliated epithelial cell?

Ah Okay, thank you. That makes sense, cell Z is definitely goblet cell then!

I was just wondering what the layer of muscle is? What muscle would that be?

It says tissue Y, so go with ciliated epithelial tissue.
Ciliated epithelial tissue is made up of lots of ciliated epithelial cells.
