The question that is given over here it consists of three different parts.
00:04
We have to answer each and every part.
00:07
The first part of the question, it says that we have to explain about ciliator's epithelial cells.
00:25
Epithelial cells are those cells that are present in the lining of all the body surface, especially that are exposed to the surrounding.
00:44
These cilia are hair -like structures that are present in the lining.
00:49
On the service of the epithelial cells.
00:52
So hence they are called as a ciliated epithelial cells.
00:56
These are only present, or mainly present on the upper respiratory tract, the falafiant tubes in humans.
01:12
This is the first part of the question.
01:14
The second part it says that we have to explain the unique structural features of ciliated epithelial cell.
01:24
The first important feature is that it has cilia.
01:28
All these are hair -like structures which have a bit lash -like movement.
01:42
And then the second feature is it produces mucus on the surface and it always keeps the surface moist.
01:56
The third important feature is the presence of micro -willum...
