Answer 1

.Pseudostratified columnar

Much of the upper airways are lined by pseudo-stratifiedciliated columnar epithelium. Pseudostratification means that despite the appearances in two dimensions, all of the cells connect with the basement membrane. The functions of the upper airways are numerous but include gas transfer, humidification, immune surveillance and clearance of foreign material. The epithelial present helps perform many of these roles.
